I disagree, and I'll bring some actual numbers to the arguement:
Before Jrue got hurt, his Month of December was very nice. 5 Double-Doubles, scored in double digits all but 1 game, had some monster games like the win against Portland where he went for 31 pts, 7 reb, 13 ast, 1 blk, 1 stl.
PPG 16.3
REB 4.6
AST 9.0
STL 1.4
TO 2.8
Next, Jrue is making 9.2 Million this year. For reference,
Ty Lawson - 10.7M
Steve Nash - 9.3M
Jameer Nelson - 8.6M
Rodney Stuckey - 8.5M
George Hill - 8M
I'd say Jrue's contract is fair and even on the "good" side.
Jrue's AST/TO Ratio is pretty much identical to Tony Parker, Lillard, Rondo, and Deron Williams. That can be improved and probably will be improved when he and AD get the PnR down to a science.
He is also 7th in the league(guards only) for AST%. He assisted on 35% of all Pelicans buckets when he is on the court. Chris Paul is like 50% and ROndo at 43%, but we are not looking for the next Paul or Rondo.
TL;DR I think you are way off based in saying Holiday is over paid.
