The way I look at it, they only have a slight advantage at one position, PG. Our PG is a little spitfire dynamic scoring machine, but his disadvantages are highlighted by being guarded by a guard like Wall. Granted we would stick Bradley or Smart on Wall on the defensive end, but going against Wall or Beal's size would represent the exact type of player IT wouldn't want to go up against.
PF would be a struggle for us, but the other 3 positions we have an advantage. Bradley > Beal, Crowder > Porter (slightly) and Horford >Gortat.
Our bench is also better. But it would be a tough series.
