Where's the trade option? What we need to do with every player who is in a slump is to trade them. Even Favors has sucked as of late; he's not hitting shots, he's lost his cool, etc. Trade them now so we can ensure getting the worst possible value for them.
Seriously, I think Gordon has lost all confidence in his shot. And when that happens, he's no good to the team. What do most "experts" say is the best way to get a guy out of a slump: you get him some easy buckets. Design some plays that get him to the hoop for a layup, then you have him shoot some short jumpers. If that doesn't work, he needs to come off the bench for a few games. Let him get some work against 2nd-tier players. And if that STILL doesn't work? Rest him for a game or two. Maybe part of the slump is related to fatigue. He didn't play this much last season. Not much training camp, few practices, more games in a shorter time span and more minutes per game. I think fatigue - physical and mental - will start to play a bigger factor from here on out. IMO, Ty needs to give all the players a game off every now and then.
