Detroit's return game question

As the Detroit Lions remain poised to host free agent WR/returner Josh Cribbs, they aren't entirely set on signing him just to solidify their return game. The club had Stefan Logan handle return duties previously, but elected not to re-sign him and he remains a free agent. In Cribbs, they could have a player who would impact special teams and the receiving game, but it's not a definite that he signs there; after all, there are other options.
