Boat has faced way more gimmick defense this year than any of those guys ever did. Memphis face guarded him yesterday, left other guys wide open and dared them to beat them. In some ways, it's similar to what Mouring dealt with as a senior - he saw more box and ones than Ray or Rip, just because nobody feared Taliek or Caron (yet) from the perimeter. Khalid and the team struggled his last year without Rip and Ricky. Ben always had Emeka and Rashad. AJP was more of a cog on a good team with five guys averaging in double figures than a lead guy having to carry a team of inconsistent teammates (I'm disregarding his first season since I don't think he was healthy).
Florida actually threw a defensive scheme at Bazz last year in the FF to effectively take him out of the game (consistent hard doubles off of high screens - Bazz only took six shots) and DD stepped up to carry us. Alas, DHam isn't ready for that or he would have dropped 30 yesterday the way he was defended. Nobody was ever leaving Giff and DD open the way our guys are left open this year. And late in the NC game last year, Boat was making as many plays in the last five minutes as Bazz.
Boat may indeed come up a hair short of some of those other guys on our pantheon of greats, and that's probably fair, but he's carried a heavy burden this year - we ask him to harass folks on defense far more than we've asked of our past stars. KEA, Bazz, Ben, would save energy at that end. Kemba would too sometimes depending on the opponent, but I think he's a level above everyone else on your list anyway.
