The national sports media reaction: "Oh no! Belichick pulled one over on the NFL again! From Brady to Cam! Hope the Bills enjoyed their offseason of thinking they stood a chance!"
The local sports fan reaction, a.k.a. the why-did-I-let-the-Boston-sports-media-talk-me-into-Jarrett-Stidham reaction: "What gives? Does Stidham suck or something?"
You'll continue to see both of those quite a bit in the coming days, but here's mine: I think the Patriots signed Cam Newton because he was cheap and because there's never been a season in NFL history where quarterback depth was more important.
That's not to say Newton can't or won't win the starting job.
