They would save more with a Brockers trade or release. Although I really doubt they'd get much in trade. Maybe a 5th rounder pick, and this due to a pretty substantial salary.

I doubt they part company with both. My guess is it will have something to do medically with Robinson. If they think he's past his medical issue with little chance of recurrence, I suspect they'll go with him as much for cap reasons as anything. He's a good player. Last year is no measure.
