But by your stats he's a wing scorer and solid rebounder. Who out there is available at 15 mil that can give us that now?
Jae Crowder (14 Points Per 36, 6.9 Rebounds per 36)
Paul Pierce (16.3 Points Per 36, 5.5 Rebounds per 36)
Michael Beazley (15.1 Points Per 36, 6.3 Rebounds per 36)
Joe Johnson (14.9 Points Per 36, 5 Rebounds per 36)
Jonas Jerebko (14.1 Points Per 36, 9.6 Rebounds per 36)
Evan Turner (12.4 Points per 36, 6.6 Rebounds Per 36)
Jimmy Butler (18.6 Points Per 36, 5.4 Rebounds Per 36)
Dwyane Wade (22 Points Per 36, 5.2 Rebounds Per 36)
Khris Middleton (16 Points Per 36, 5.3 Rebounds Per 36)
Danny Green (14.7 Points Per 36, 5.3 Rebounds Per 36)
Rodney Stuckey (17.2 Points Per 36, 4.8 rebounds Per 36)
Josh Smith (16.9 Points Per 36, 8.4 Rebounds Per 36)
Paul Millsap (18.3 Points Per 36, 8.6 Rebounds Per 36)
I could probably find more if I start going through more stretch fours (e.g. Millsap) but that will do for now.
I think every guy on that list is either (a) significantly better than Harris or (b) would cost us significantly less than Harris...and I don't think many people on that list would have a worse 'Real Plus Minus' than Harris, since his is well...pretty bad.
But I can look it up for you and confirm for each if you like.
Also don't use three point shooting as a criteria to further narrow down that list since (as per my previous post) Harris has not even been nearly consistent enough over the course of his career to make anything close to a compelling argument for his ability as a shooter.
