Even though Nolan cut his teeth by running 3-4 defenses, it's unlikely we transition to that anytime soon with the way our personnel looks. Seems like an easy call that we'll stay with a 4-3.
In looking at what Nolan really like in his players, it amounts to the following:
1. Big bodies in the middle to help take on blockers and keep his LB's clean
2. Small,quick DE's (260 lbs. or so) valuing pure speed and bend over size
3. Linebackers who are quick and can run. Blitzing, ability to track backs and TE's off the ball
4. Cornerbacks that are long and rangy
With that in mind, I would expect our DT's to get beefed up a bit. Guys like Javon Kinlaw, Leki Fotu, Marvin Wilson fit the profile of run stuffers who could help bolster our inside
