Eaton was some player in his prime. In NE, his versatility was special, and it was not unusual to see him either gaining or losing 30 pounds in an offseason at the request of his HC. There was no weight problem on his end, just the demands of playing 3-4 or 4-3 dt. He was a press and fan favorite up here, for good reason.
When the Seahawks released him, they made a point of saying it was not an injury related move, but a cap consideration. But it came across as protesting too much.
How many snaps he's needed for and how many he can hold up to will probably decide his fate.
