There are a lot of problems for the Pats, mostly with people being overrated (Adalius Thomas was a 99 for example......). Also, the depth chart is for a 4-3 defense, while the Pats run a 3-4. Adalius is listed as a defensive end, which he would in a 4-3, but he plays 3-4 OLB for us.
I'm not gonna go through the entire list, but I'd say more than half my roster is 4-5 points overrated, if not more, with a few that are underrated. This almost seems like the old inflated Madden rankings before they watered them down last year, I dunno.
