Xavier Tillman Sr.
With the Memphis Grizzlies having a rough year and with them already trading Steven Adams, it's clear they are sellers. Memphis has a lot of bigs coming back next season (Brandon Clarke, Jaren Jackson Jr. and Santi Aldama) and Xavier Tillman Sr. will be a free agent.
There are reports that Tillman could be available and the Heat should kick the tires. He's not as big as Drummond but, at 6-foot-8 with a stout frame, he can provide some depth at both power forward and center. He's passable defensively and has flashed the ability to make 3s (48 made 3s in 3 1/2 seasons). At 25, he'd be an interesting development project for this Heat coaching staff.
