Well it had at least a little to do with size - after all, NO has pretty good size with Favors and Ingram and Zion and even Ball and Holliday at the guard position - but I just watched the last three quarters of the game last night, and you were right about the effort. Well maybe not effort but there were a ton of mental mistakes that lead to wide open shots.Yeah, I remember this possession. It had little to do with size, and everything to do with absolutely no effort. I think I turned the game off after that specific possession, because if they weren't going to care, I wasn't either.
Size/rebounding isn't so much this team's issue (statistically and eye test). Perimeter defense/offense/effort is where they live or die. On that note, I'm also concerned they don't have enough shooting--that will kill them against long, athletic teams like Milwaukee and Philly that can take away their usual physical dominance on the wing.
According to BRef PbP, NO got 6 offensive rebounds in one possession. It looks like the starters (DT, GH, JB, KW, and MS) were in for the first two ORbs, and Wanamaker sub'd for Kemba before the last 4 ORbs.
