The problem with this team is that they've got the cavalry coming in for offensive purposes in the form of IT (still, that's assuming he's healthy by midseason which is no gimme), but there is no chance they become a good defensive team this year. Outside of Lebron, who himself is prone to defensive lapses, who's a plus defender on that team besides maybe Shumpert?
This team will comfortably make the playoffs -- please remember that the East still stinks, by and large -- but yes, they're in trouble. The Celtics, Bucks, or Raptors could easily be the #1 seed this year.
