Sure, we couldn't guard anybody with a decent post player, nor could we rebound when we had Brown and Justin Taylor as our big men... Our roster is worlds better than the last two years.
But we still are going to see a handful of 7' 265lb guys this season, and having no answer for them isn't exactly a comfortable place to be.
Almost every single P4 team we are playing against this year has at least one player bigger than our biggest guy. If you exclude Diawara when you consider he is unlikely to play much, it gets even a little worse.
We are putting a lot of faith in our three guys listed 6'8-6'9 and 225-235lbs when the other teams throwing out guys both taller and heavier. White is listed at 195 and Freeman 205...
We might be able to play them against mid majors at center, but we're looking at a race to see who fouls out first if they try to guard 7' 265 lb centers.
