I think this is all part of Belichick looking to combat the Chiefs, Ravens, Bills, etc.. Increasingly, NFL offenses are RPO looks with lightening fast offensive weapons running laterally across the field and quarterbacks who can exploit holes in the defense with their legs. How do you defend misdirection with speed like this while avoiding being gashed by running QBs? With a millions in-the-box safety types and smaller, fast linebackers. We could potentially have a combination of Chung, Phillips, Duggar, Uche, J. Williams and even this kid from Wyoming, Maluia, on the field. I think they are all being brought in to try to cover these offenses as well as covering tight ends and slot guys running across the middle of the field. They are all bigger hybrid guys who will, I imagine, line up at linebacker, off the edge, as well as at safety and look to punish running quarterbacks and wideouts running horizontally across the field. I'm actually excited to see what Belichick is looking to build defensively this year. I think he realizes that the future of defense has to be with this kind of hybrid look and nearly all their defensive acquisitions seem to have this concept in mind. Everyone looks to the Titans game at their Achilles heel but the Titans offense was nearly unique in the NFL and besides, the Pats defense gave up 13 points that day (it was the offense being unable to score that cost us that game). Rather, it was against Baltimore that the D really struggled and it looks like we're undergoing a rebuild with that in mind. I wouldn't be surprised if we carry about twenty safeties.....
