A guy who can fill it up like Monta isn't something I would disregard. Have we had somebody we could count on for 20+ since Kevin Martin (not counting the contrived 20-5-5 Tyreke season where the organization did cartwheels to get him that 20 ppg)
You can't make Ellis work with our backcourt unless you run him as co-point with Tyreke. Tyreke can defend the 2s, and Ellis can let the 1s go by but probably outscore them. I like the concept of pick and roll offense with Ellis and Cousins, but a strong defensive point guard would work better as a change of direction for the team. There are a dozen options that fit better, though. I only start looking at Ellis if you can bring back Ellis AND Tyreke and ship out 2 of our other three guards.
