I don't see a problem with keeping Koufos. He's a solid backup center, and is fairly consistent in what he does. Actually I can see a three man rotation working just fine with Cuz, WCS, and Koufos. The problem starts when you enter Gay into the equation at PF. Keep Gay at SF, and it's not a problem, unless you see Casspi as our starting SF. If so, then you have to trade Gay. Personally, I have mixed emotions about it. I like Gay, but he only plays defense when he wants to, and he has trouble resisting the urge to dribble the leather off the ball at times. He has trouble rebounding at times. This season in particular, he's been very inconsistent. Easy to blame Karls system for that, and that in fact may be part of the problem, but, I've seen games where he's operating within the system, and he's played very well. So not sure. Gay is certainly athletic enough to play at a faster pace, and I'm sure it's not part of Karls system to dribble into double and triple teams. Especially after passing up an open shot on the perimeter. There's enough blame to go around for everyone.
