Well keep in mind, the Knicks didn't have Curry during the time QRich made those comments. Having Curry down low in the post, pretty much rules QRich out of playing there. If the Knicks were using Jerome James as the starting center, then I could see QRich have more opportunities to be the post scorer.
The main reason QRich is not getting a chance is his own fault though. If you don't play defense for Larry Brown, you aren't going to play. It's that simple, and QRich can mope all he wants, but until he commits to defense he's going to be in the doghouse. Larry Brown always has a whipping boy, and QRich has played the part. It used to be Crawford, but Crawford has improved the way he plays and is even giving the Knicks some defense. A lot of teams could still use QRich, but he has to be back on the inside posting up guards. I think a team like Seattle would be a good fit for QRich, because they don't really have a legit post up player. Having him on the court with Shard and Ray Allen would be tough for teams to match up against. I also think he'd be a great fit on the Lakers, because the Lakers also don't have strong finishers in the post. Maybe more touches inside will get him motivated on defense, so the Triangle could work out for him. Unfortunately his salary wouldn't work in the 2007 plan, so he's automatically ruled out.
