8. Hasheem Thabeet
Stats: 2.3 PPG 2.8 RPG 0.9 BPG
Teams: Grizzlies, Rockets, Blazers, Thunder
Drafted No. 2 overall by the Grizzlies in 2009, this 7'3" giant from Tanzania drew comparisons to Dikembe Mutombo for his shot-blocking prowess, and if we're being honest, continent of origin. Thabeet's been on four teams in three years, and has been an immobile heap of weight on defense while contributing next to nothing on offense. For someone who's supposed to be a great shot-blocker, a career average of less than one block per game is pretty sad.
