Tim W, i have to disagree with you.
I am a big believer in advanced stats and the contribution to wins besides scoring. But this doesnt justify overpaying for these other skills. I really liked what Amir brings to the table, hell i even said that when the trade went down:

But he is good value at 3-4 million/season, not 7. Also, it is not a good deal when you are rebuilding and want all available cap space.
According to basketball-reference, some comparisons:
Johnson: TRB%: 16.1, ORTG 124, DRTG 110 TS%: .639
Collison: TRB%: 16.1, ORTG 120, DRTG 105 TS%: .616
C.Anderson: TRB%: 16.5, ORTG 126, DRTG 103 TS%: .631
R. Lopez: TRB%: 15.6, ORTG 123, DRTG 110 TS%: .621
Brockman: TRB%: 19.2%, ORTG: 124 DRTG 110 TS%: .564
Penegraph: TRB%: 15%, ORTG: 130 DRTG 105 TS%: .705
What I am trying to show is that the skills Johnson provides are the most replacable via the draft. Signing players to long-term contracts negates the value to wins they provide in the first place because you are overpaying for that. Also, I actively tried to pick players who were undrafted/late in the lottery or draft to show how plentiful this type of player is. Players like Varejo, Horford, and the Gasol brothers easily post better stats than Johnson.
