Kevin Gemmell We're continuing with our under the radar series. The idea is to pick out a player who is not a big name, but who may be underrated. Or, at least, a guy who will need to step up and play a critical role in 2012. We're going in reverse alphabetical order. Colorado: DE Chidera Uzo-Diribe 2011 production: Totaled 18 tackles -- all solo -- and had 5.5 sacks. He also forced a team-high three fumbles. Making the case for Uzo-Diribe: Of the eight defensive linemen named to the first and second team all-conference defense last year, only two of them (Nick Perry and Dion Jordan) had more sacks than Uzo-Diribe, who finished ninth in the conference.
