Very good signing given the circumstances. You aren't getting another JJo in week 13 looking at street FA, but the guy has speed to burn and if Vance Joseph can take Kareem Jackson and turn him into one of the better #2 CB's in the league, maybe he can turn Routt's career around too.
I think a lot of it depends on Routt. If he's a problem child he won't be here long. If he takes coaching, works hard, keeps a good attitude, and is a good locker room guy, he could thrive here and actually be an upgrade long-term. Interesting signing with very little downside risk.
Kudos again to SmiPhilliak!
