That's actually not true. At different times Carmelo was guarded by Hayward, Booker, Ingles and Burks.
Getting inbound pass to a capable shooter is not always as easy as it seems, especially when the opponent sags off of the one that they want to get the ball in order to help covering the other 4. In general you get a situation where 5 defenders try to deny a pass to 3 players and are perfectly happy with giving the 4th one the opportunity to get the ball and foul him. Also, you have no idea what kind of play he draws and if the problem is with the plays themselves(problem with the coach) or with the execution of the plays(problem with the players)... or simply because of great defensive effort by the opponent.
Also... wow! Decent shot with 2.3 seconds? Pretty much what you rely on in 2.3 seconds is that the opponent will screw up a defensive assignment or a switch. If that doesn't happen you are not getting an open shot. EVER!!! Any shot that you get facing the rim is a decent shot with 2.3 seconds remaining.
Chucker won us the game and have been playing relatively well in the last couple of games. Exum has been struggling on the road and is not ready to start. He gets abused every game on screens and has not been great initiating the offense. He's been deferring a lot, he's been giving up his dribble a lot. People around know that I am probably one of Dante's greatest fans, but he still looks like a kid among men in huge portions of the games. Until his body catches up with his skill and talent, I would have no problem with Dante coming off the bench as a sub.
What I haven't liked from Quin is him taking out players with 2 fouls in the second quarter - this one I definitely think is a mistake that has already possibly cost us one or two wins.
