Your bench is lacking in offense.
Not as much as you think. These are generally all reserves, besides Ball, and playing reserve minutes. With heavier minutes and responsibility all of them will up their output, but that really isn't needed. How many teams in the NBA have a 20 pt scorer off the bench?
I really just need a group that can hold their own for 5 minutes at at time, and all are plus defenders (or even) and all can score. I have solid facilitation as well, and tough perimeter D. I also have 3 pt shooting across the board and solid rebounding. They aren't going to win games alone, but they provide a rest for the big guns and some real matchup problems with a mix-and-match possibility.
Picture Baynes/Davis/Warren/Brooks/Curry with a 3 pt threat at every spot, scorers at every spot, elite D at 3 of the 5, and passable D at the other 2, and 5 players that must all be respected on the offensive end. Curry and Davis will have a field day with these possibilities. I can do the same thing for tighter D, or run and gun, the options are endless. Best of all, all of these are great role-players who will have no problem playing to highlight and support the stars.
I am not saying this is the best team in the whole thing, that is for the fickle fans and faulty simulators to decide, but imo this team is a tough out for anyone.
