There are so many things that go into being an effective post player. 1 or 2" certainly doesn't matter if you have a 7' wing span. If you're 6'8" with a 6'5" wing span you will struggle to be an effective big man against D1 teams with multiple players over 6'10" (and no I am not saying Braxton has a short wing span). Adrian Dantley beat some of the best post players of his day at maybe 6'5" but I am sure the Jazz wished he was 7'. There are also some 7' players that are soft as a marshmallow.
Foot work, jumping ability, court vision, strength, speed down the floor, reaction time, toughness, rebounding, shot blocking ability, are a few things that come to mind, and yes ... height does matter. The thing I like about our team next year is that it appears we may have more options than ever before to excel in the post, both on offense and on defense.
Isn't this potentially the deepest we have ever been at the post position?
