I agree with this list, but I think you left a guy that has surprisingly been a disappointment this year:
Raymond Felton
Yes, the guy has been injured and the guy sometimes plays with tenacity and fire penetrating through what seems the whole oppoaing team.
But what we needed from him was to steady the offense, make sure the ball kept moving and get guys like Melo, Amar'e and Chandler the ball where they like to. Yet its really been a mess on offwnse, especially since his return. Oh, and do we talk about his defense? He was never this horrible his first time around. Wth!
I really thought we were set as a team once Shumpert came back, but now I believe we need to upgrade PG and even starting SG because Shump is still an offensive liability, only with no defenae this time around. And yea, both players maybseem to be excused because of the injuries, but that is a big problem with this team, they always get the free pass:
The lost because its hard to be motivated against a bad team.
They lost because they played a better team.
They didn't play defense because... I'm not even gonna try becaue that one is inexcusable.
