I found a blog were it seems they get quotes from Sam Giguere from time to time. I went ahead and applied a Babelfish French to English translation for everyone.
On the most recent entry it looks like Polian has promised to try and activate him before the end of the regular season. He also says in another entry that Special Teams coach Ray Rychleski really likes him. I don't know if that means for returns or just on coverage teams.
I remember him having 1 return during the preseason, but it was awful! Yet, there could be some ability there, as it appears he's just now feeling healthy from the leg injury during the offseason.
