The Panthers and Bears almost shuffled nickelbacks, with the Bears offering a one year deal to Captain Munnerlyn this afternoon. Carolina apparently countered with a 3 year, 5 mil deal before matching the Bears' offer, and Munnerlyn took it, to stay.
This gives Munnerlyn the edge, in my opinion, to start in 2013. Munnerlyn improved drastically in 2012 under new DBs coach Steve Wilks, after struggling heavily in 2011 as a first year starter. While he lost the starting job to rookie Josh Norman, Munnerlyn flourished in a second chance after Chris Gamble went to IR, playing well at both the nickel spot on passing downs and RCB on early downs. profootballfocus.com gave Munnerlyn a +6.4 rating in coverage.
If Munnerlyn does start, it at least does give two starters to return. Gamble retired after being released - the pairing of Haruki Nakamura and Sherrod Martin isn't likely to see the light of day again, with Nakamura taking a pay cut to return and Martin being a free agent, replaced earlier today with Mike Mitchell.
