When you say "good" are you referring to only rebounding or as a player in general?  I put Ivo firmly in the good category as a player in general.    He covers his shortcomings on defense and rebounding by being an excellent offensiver player.  If he commits to developing defensively and using proper rebounding technique as he has to developing his offensive repertoire he has the chance to have a great senior year.

When comparing the current crop of players versus years past keep in mind the systems are completely different. The current offensive scheme does not require the wide body in the post, but rather athletes who can run the floor continually.  As long as the current system is in place I don't think you'll see the dominant low block post player but rather pick and pop style bigs.  What matters is the end result, I'll take 12-2.
