This regime didn't surrender that for him; the old regime did. That's not McDermott's problem, and it's a sunk cost anyway. I think Watkins wants out (why wouldn't he want out given the circumstances???), and I think McDermott wants guys who are "all in." I also think that the foot is a real wildcard here.
In any event, I don't expect the Bills to pony up $17 million for a one-year deal with a WR. I like Watkins a ton, so I hope I'm wrong. But we've been down this road before.
