I like Moore better at safety than corner, although that may just be because it's easier to see his breakdowns at corner because he's in the frame. Aside from some focus on the big hit instead of the sure tackle, I thought he did fairly well at safety before. Still, absent the coach's tape, it's hard to adjudicate.
I think we may see McCourty back at corner with Ighedibo at Safety and Moore/Edelman as nickel and dime backs. My guess is that they didn't know how long Chung would hold-up last week, so Ighedibo practiced at Chung's safety spot and they entrusted the other role to McCourty. With the Bill's relatively weak receiving corps after Stevie Johnson, they thought they could get by with a weaker CB group, but I don't think they go that route in the playoffs. I feel pretty good about that group of six, although I'm sure we'll see a little Molden, whereas Brown won't see the field unless somebody gets hurt and Jones might be the odd man out.
Of course, this all assumes that Earthwind Moreland isn't signed.
