All due respect, but
1) the Thunder are getting it done this postseason with versatility and perimeter defense. The turning point against the Warriors was Donovan's decision to invert Ibaka and Roberson's roles on offense, letting the latter cut to the rim and score on the catch, and his quick trigger to go small with the Russ/Dion/Dre/KD/Serge lineup which is just mutilating Golden State's "Death Lineup" per minute in +/-. Scott Brooks, the size purist, had trouble letting go of lineups with Kendrick Perkins until the Kanter trade last year and the 2012 Finals should have ended the fantasy for him either way.
2) Khadeem Lattin lead the Big 12 in blocks/36min as a sophomore. Jamuni, in limited minutes, has shown a knack for pinning 'em to the glass. Rim protection is a skill, and you can never have too many skilled guys who are 6'8-6'10. But that's why Kentucky, Duke, UNC, Kansas, UCLA etc. always seem to have them all. It's a premium recruiting commodity.
A Roberson - lite player, whose versatility and motor and strength relative to size lets him overcome 6'7/210 measurements as a college post, gets you wins in college. Orlando Allen and Casey Arent do not.
