I thought that the refs last Sunday did an excellent job, they called the obvious re-routing of the WR on the Balt int (I think the flag came out only after the int, but at least the recognized that they had to call it). They called the obvious penalties, I can't remember a single offensive holding call (note to Pats lineman, hold like the Giants did in SB 42, they are not going to call it). But I thought they let the boys play, they called the blatent fouls and let everything else go.
This I think has hurt the Pats in the playoffs the last few years, the Jets mugged our recievers last year and got away with it. Hopefully our WR will take a lessen from Branch and push off, as they seem to let that go too (cough, cough, again Giants in SB 42).
I would have Gronk just run straight up the field into whoever is covering him, smash into the DB/LB, bounce off him, turn around catch ball, all is good.
Look nobody wants a SB with flags everywhere, so they let certain things go, I guess the trick here is knowling how much you can get away with.
