I've been wondering this recently - did the Pats know they would be primarily a 4-3 base defense team this year when they drafted in April? And if not, would it have changed anything? Am I wrong, or were they running 3-4 in minicamps? It seems to me that 4-3 was something that arose in camp when they realized a) Mayo was the cornerstone of the defense now, and he could be best utilized as a 4-3 MLB, perhaps b) with their personnel at OLB, 4-3 gave them the best chance to win. Looking at who they picked - looking at the D-linemen, there's certainly a lot of versatility there and all those guys can play in either a 3-4 or 4-3. Their only pick at linebacker was McKenzie, and to me, it seems like he was drafted to be a 3-4 SILB, but we know he played 4-3 OLB in college. I do wonder, if they had known they were going to play more 4-3 back in April, would some of those edge rushers - the DE/OLB hybrid guys - have been more in consideration?
