The bills trades make sense for them. Yeah getting rid of Watkins sounds dumb on the surface, but they didn't sign his rookie option, this is his last year on his rookie contract, and they're very clearly going nowhere this year + have a rookie head coach. Watkins was either gone in FA or he was going to be a massive investment coming off 1 year of good play. Too much of a risk for a team going nowhere, especially since they just drafted a WR in the second round this year.
They're stacked with picks, so they have some draft capital plus they're realistically a 5 win team this year now. They've been "mediocre" for way too long with no playoff potential. Best to just start a fresh rebuild.
I like the Watkins move for the rams too. Gotta build around the #1 pick no matter what. If Goff manages to breakout that could be a fringe playoff team, all depends on how he plays.
If Darby manages to bounce back it'll be a good pickup for the eagles. Worse trades have been made tbh.
