Unseld was great, but short

I am very concerned about our lack of height this season, and it is primarily on the defensive end, since the 3-point shot has made size pretty irrelevant on the offensive end. Wes Unseld was an all-time great, and he played center in the NBA, and he was only 6-7. BUT, he did have trouble guarding Kareem Abdul-Jabbar. OK, so everyone had trouble guarding Jabbar, but Unseld gave up seven inches to him, and really looked overmatched. I am afraid that is how we will look this year against good big men (although probably not quite to that extent). Good defensive technique and good team defense can help overcome that, especially at the college level, but it is still a problem.
