For the past week, I've been thinking a lot about this thought from Brother Pa:

BB has started to assemble a group of "interchangeable" elements at EDGE and LB. Chandler Jones, Dont'a Hightower, Rob Ninkovich, Jamie Collins, Akeem Ayers. All can play in space and come off the edge, and all but Jones can play ILB to some extent as well. That gives BB tremendous versatility to mix and match guys and move them around pre- and post- snap. Mike Reiss referred to this as the "interchangeable defense" against Denver:

What if, instead of a big fatty in the middle, the Pats had a bunch of uber-athletic, versatile, interchangeable moving parts on the DL? Dominique Easley already falls into this class - a versatile guy who can play anywhere from the 0/1 to the 9 technique. What if, instead of spending a high pick on a wide body run stopper, the Pats invested in day 2 versatile athletic guys who could be moved around and interchanged?
2 guys in particular come to mind:
1. Marcus Hardison, Arizona St. 6' 3 1/8" 311#. Manx has been touting him for months. Highly athletic former QB and JUCO transfer, who had a breakout season this year with 15 TFL and 10 sacks. Reportedly has 4.7 speed, and shows great explosiveness coming around the edge. Played mostly outside as a DE in Arizona St.'s complex attacking defense, but has also played inside, including at the nose. Needs to develop his combat tactics to play inside, but has ridiculous versatility and upside. The following is a nice read:

2. Mario Edwards, Florida St. 6' 3", played anywhere from 294-320# this season. Like Hardison, played mostly outside at end, but may project best inside at the Pros. Jimbo Fisher notes that he can play anywhere from the 9 tech to the nose:

In a 5-2 base the Pats could have all 3 guys inside, paired with 4 EDGE guys. In sub you would take 1 out and replace him with a DB. In both cases there would be lots of potential to move guys around and create mismatches. All 3 can rush from the outside as well as inside. None are prototypical 2-gap players or run pluggers, but the gain in versatility and pressure would offset that to some extent. Dominique Easley showed nice development this year in terms of his gap control and edge setting ability, so I think that there's a good chance the Pats could coach these guys up. In situations where a premium run-stuffer was needed, the Pats could substitute in someone like Siliga or Branch.
It would take something of an adjustment, and is undoubtedly a bit of a long shot, but it would be a very interesting defense.
