The Cyrus Jones stuff is very interesting to me. On kickoffs, Belichick said that communication was screwed up. I think the Patriots want to be unpredictable by running some out of the end zone, and taking a knee on others. You can't break a big one if you don't take a shot once in a while.
On the personal foul, I like that Jones has some fire and pushes back when provoked. He won't get the benefit of the doubt from the refs as rookie. Amendola and Edelman constantly get in the face of opponents, but they've earned the right to inform bullies what they can pound when they pull their stunts.
I'd be surprised if Cyrus Jones gets cut, but I would not be surprised to see him on the Inactive list or even on the Practice Squad if they think he would clear waivers. He has to learn that he does no one any good by getting thrown out for unsportsmanlike conduct.
