Peja would be the PERFECT fit for the bench unit. Whether it be Shaq or Perk, having more shooters around the perimeter to catch spot up 3s is what we've been missing.
Now Peja might not be a decent defender, but he is long enough and smart enough to play 10-15 MPG guarding back SFs(James Jones,Luke Walton,etc)
Peja also shoots at a high percentage(FTs and 3's) and can light it up like Nate, plus his presence alone would open up other players like West and Nate for 3's or slashing to pass to Shaq and JO for easy buckets.
