I hate to throw a bunch of stats out, because they can be so misleading and don't necessarily prove anything, but last year against us, and in the 2 games vs Raheem's Falcons, Gronkowski caught a total of 7 balls for 83 yards.
However, in those same 3 games Antonio Brown caught 24 for 288 yards, Evans caught 14 for 205 and Godwin caught 16 for 122. Admittedly, most of those numbers came against the Falcons, and we have a much better secondary. (vs. us, they caught 8, 5 & 7 respectively) It tells me Morris knows how to cover the TE, but maybe not the WR's.
I think we've got the people and plan to keep Gronkowski in check. If we're lucky, he'll be blocking most of the time.
I really don't like the match-up of their WR's against our 7 yard soft coverage bubbles.
