A Paul Millsap for Tyreke Evans would be a pretty interesting trade.
PG: Tyreke, Mo Will
SG: Hayward, (Tyreke)
SF: Marvin, (Hayward)
PF: Favors, (Big Al)
C: Big Al, Kanter
Not sure how good a fit Millsap would be but he may be the most talented player (current ability) Sacramento could get for Tyreke Evans. There would need to be some subsequent trades with J.Thompson or T.Robinson to re-balance the lineup. I think Millsap would be very good for Cousins.
