Read here. All indications are that Colledge is leaving. Apparently he will be signing with the Cardinals. Colledge was solid last year. He and the line came together nicely especially down the stretch. I also happen to think he’s a decent person who fit well with the team despite often being the target of criticism.
That said, Colledge was not an All-Pro and another player should be able to slide in there without much problem. In fact, I’ll take it a step further and note that with another guard in there our line may be better overall (especially in the running game).
