Boy, that's dumb. He's not that good and his (or anyone else in the NFL) career could end on one play.
Since I have felt Keller has long been overrated by too many Jet fans, that he has no upside, disappears in games too often, now is showing signs of fragility, and has always been a poor run blocker, I hoped the Jets would not try and keep him. Certainly not at too high a price. Therefore this is one non move I am happy about. And if he's gone to Miami, I wish him a career death, sooner the better.
