A player who’s already on the roster could also be at risk of losing their spot to one of the new guys. I’ve pegged Dexter Pittman as the player most likely – he hasn’t improved much over his two seasons with Miami, and did not perform up to expectations in Summer League, averaging only 4.3 rebounds throughout. In addition, he was very foul-prone, and lacking the basketball IQ or post skills necessary for an NBA player. However, he is a big body, and that is one of the few areas Miami are in need of at the moment, so Pittman may very well make the cut.

Terrel Harris is a serviceable, blue-collar player who plays his heart out every night. It was his solid performances in last year’s preseason that earned him a spot on the Miami Heat, and he justified his selection by turning in good shifts whenever called upon. In Vegas this year, he proved to be an effective performer on both sides of the ball – highlighted by one particular game where he made San Antonio Spurs guard Cory Joseph look helpless. The result? Another contract from the Heat, and what should be a guaranteed roster spot.

Mickell Gladness has been here before. He started the season with the Heat, but ended up being released midway through the season and settled in Golden State for the remainder of the year. He is a decent post defender, but lacks bulk on his 6’11 frame, and his offense could be called just that – offensive. The thing is, Miami already has a more experienced version Mickell Gladness on the roster. His name is Joel Anthony. And there’s only a need for one player like that on any squad, much less the Miami Heat. As a result, I see Gladness on the outside looking in.

Jarvis Varnado is an extremely intriguing prospect for the Miami Heat. A second-round draft pick in 2010, he made his name in college as the NCAA’s all-time leader with 564 blocks. This guy can jump all across the gym, and his 7’4’’ wingspan makes him even more intimidating for opponents to shoot over. His basketball instincts are all very good, and rarely gets beat on shot fakes. His offensive game could use some work though, as it’s almost as bad as Joel Anthony’s – but he makes up for it with his quickness, length and ferocity. Varnado’s got a great shot of making the grade for the Heat this season, as his abilities will be useful if needed.

Garrett Temple is an interesting case. Since being undrafted out of LSU in 2009, the 6’6’’ shooting guard has been a total journeyman during his brief career, with stops in San Antonio, Houston, Sacramento, Milwaukee, Charlotte, the D-League, and Italy before joining Miami. He offers a decent amount of scoring, and compared to other shooting guards on the roster (Dwyane Wade, Ray Allen and Mike Miller) he’s still fairly young, and is less-injury prone. That’s all he’s got going for him however, as the Heat really like Terrel Harris, and shooting guard isn’t exactly a position of need at the moment. Expect him to be cast aside as the season draws closer.

Lastly, we have Josh Harrellson. Jorts, as he’s sometimes known, was a member of the New York Knicks this past season, playing in 37 games and starting 4. He’s earned a reputation for playing to his strengths, garnering a decent rebound rate and offering a physical presence down low, something Miami could always use. His shooting ability is decent for a man of his size, and can even knock down a 3 if needed (which won’t be often – Miami already has a long list of shooters who can do the job). There are a few knocks on him, the most obvious being his lack of athleticism. Also, he’s guilty of being too physical on defense, although this is probably to compensate for his below-average mobility. He does work hard, though so it’s very conceivable that Harrellson earns a spot with Miami if he puts in the effort needed.

For those keeping score, of the 6 players profiled here, I have Terrel Harris and Jarvis Varnado as two of the players making the Miami Heat opening day roster. Conversely, Mickell Gladness and Garrett Temple will end up being future endeavored after training camp. This brings me to the last spot contested between Dexter Pittman and Josh Harrellson. Both have big frames and are obstacles in the post, and both suffer from a lack of quickness. In the end, I see Josh Harrellson taking the 15th and final spot on the Miami Heat. Dexter Pittman hasn’t made much, if any progression during his tenure in South Beach, and his struggles during Summer League only intensified the questions surrounding his work ethic. Harrellson can at least help to stretch defenses, and is a smart player who can compensate for his athletic faults, so his versatility will be useful for Miami.

With that, here is my proposed opening-day roster for the 2012-13 Miami Heat:

LeBron James, Dwyane Wade, Chris Bosh, Mario Chalmers, Shane Battier, Ray Allen, Mike Miller, Udonis Haslem, Joel Anthony, Norris Cole, James Jones, Rashard Lewis, Terrel Harris, Jarvis Varnado, Josh Harrellson.

Not a bad-looking lineup, no? Especially compared to the squad at the beginning of the Big 3 in South Beach.

The aforementioned players may not get much, if any time to prove themselves this season, as Miami looks to build on a spectacular year and possibly challenge for 70 wins. But should the time arise, they would be the three players I would have on the roster ready to answer the call when needed. These guys will look to make their mark when the opportunity arises. But first things first – they’ll have to confirm their place on the team. Then they can think about making a case for a rotation spot.

Of course, he’ll have to earn his way on. Like Mickell Gladness and Jarvis Varnado a week earlier, Harris was signed to a non-guaranteed deal that will have him practicing with the Heat, but with the possibility that he could be let go. Miami is allowed to bring 20 people to training camp, but most whittle it down to 15 by the beginning of the season, which is October 30th.

Before then, the Heat will have training camp and eight preseason games, starting on October 7th against Atlanta, to decide who the final two players will be to fill out the remaining two spots on the roster.

Harris could be one of the player more likely to make it because he was a part of the championship team from last year. In his rookie season as an unsigned guard out of Oklahoma State, Harris played in 22 games, started one, and averaged 3.6 points, 2.3 rebounds and 1.2 assists per, while converting 35 percent from the field and 21 percent from beyond the arc.

Obviously, there are things Harris can work on. But Miami has seen what type of potential Harris has in him, with a key example being his tremendous effort in a triple-overtime win against Atlanta early in the 2011-’12 season. With Dwyane Wade and LeBron James sidelined, it was Harris stepping up at every facet of the game and finishing with 9 points, 14 rebounds and 4 assists in 39 minutes worth of action.

Harris is quite the aggressor on the boards, despite only being 6’4″. He also had 10 points, 6 rebounds and 4 assists in 26 minutes in a loss to Memphis and 8 points, 6 rebounds and 4 assists in 35 minutes in a win against Charlotte.

Signing Harris represents the Heat signing for the future–a rarity. Out of the 16 players under contract with the Heat, eight of them are 30 years or older and nearly all of them represent a significant spot in the rotation. James, Chris Bosh, Mario Chalmers and Norris Cole are the only players under 30 who could boast significant minutes, and even Cole could be excluded from that list considering how he fell out of rotation last year.

Harris was one of four Heat free agents. Ronny Turiaf, who signed with the Los Angeles Clippers, Juwan Howard and Eddy Curry are the others. The Heat haven’t addressed matters on signing Howard or Curry, who recently met with the Brooklyn Nets.

Harris will be evaluated based on his performance over the next month. The Heat want to see the same defensive intensity and aggression on the boards, as well as a more consistent jump shot. With Dwyane Wade, Ray Allen and Mike Miller being the primary shooting guards, an injury is always possible and Harris would need to be ready at all times to take on the role of a rotation job.

Former Heat draft pick Robert Dozier will also possibly join the team with a non-guaranteed deal. The 60th pick in the 2009 draft has spent his basketball playing career with Colossus Rhodes and PAOK BC of Greece, as well as Cholet Basket, a French team. He has yet to play in the NBA, but has been on a number of Summer League rosters including the most recent one where he averaged 3.7 points, 3.7 rebounds and 1.3 assists per.
