Is there enough space to continue to add the pieces to make them upper tier?
Well they are banking on natural improvements from guys so young. Plus, right now what do they need outside of time, more shooting, and another backup big? One of those cant be bought and the other 2 can be found quite cheaply.
But the players and their deals give the team flexibility. Say a blue chipper is available, a Pels package would be stout. Or the pieces just dont fit, they can use assets to reconfigure the team.
