A few on that list that need clarified
Mark Herzlich-Love the story and going to BC obviously would make him an instant fan favourite, but he would be an ILB in the Pats scheme and that position is stacked.
Travis Lewis/Bruce Carter-Once again wouldn't be able to play OLB in a 34
Von Miller-Looks like he will be a DE playing OLB, ie he will be a stand up pass rusher and nothing more. If he can't show he can set the edge in the run game and also drop into coverage then he will be off the list.
Mark Ingram-Ingram profiles as a pound it out workhorse type of back. I dont think the Patriots will be in the market for one of these. Williams is more of a do-it-all back and would be the choice of the two IMO.
