Jax is an inefficient shooter, but he also creates shots for others. That's something neither Salmons nor Maggette ever did. Maggette I agree with, Salmons I don't. He averaged 3.5 assists in his time here with awful offensive players. Jackson has averaged 3.6 the past couple years with similar awful offensive players. Don't ignore Shaun Livingston in this trade either. His Player Efficiency Rating was pretty good last year First of all, PER is a garbage stat. Sundiata Gaines was rated the 10th best SG according to it in 2009-2010 ahead of Kevin Martin, Ray Allen, Eric Gordon and James Harden. Second, his PER was like 14.33, 15 is average so unless by pretty good you mean below average, then I agree his PER was pretty good.
