Ty Warren injury latest concern on New England Patriots' lines - ESPN Boston With the injuries/non-participation issues going on with the DL I wanted to pose a question to the board. Will the Pats be forced to go to more 4-3 because of the injuries? Gerrard Warren and Lewis are both comfortable in the 4-3, and a lot of people say Pryor and Wright are more cut out for the 4-3 and Wilfork played the 4-3 in Miami so I think the DTs are all set. This would make TBC, Cunningham, and Ninkovich (Burgess if he shows up) DE instead of OLB. Who becomes our OLB and MLB? I think Mayo is the starting MLB, and Guyton an OLB. Do McKenzie and Spike have the skill sets to be OLB in the 4-3? Thoughts?
