It's not an unreasonable fear to have right now. We know that Todd has been on a touch count. We know he dealt with a pain issue that reoccurs in the playoffs. We even heard him say he was about to give the Rams some money back when it started, something along those lines.
I think he's going to stay on a touch count through the regular season, and that this is who he is now. Whether he gets bigger snaps in the playoffs is not certain. If it's a deal like Thurman Thomas had, his is probably a worse condition that has to be watched more carefully. I also think Todd is tired of it, of not being himself, and it shows in the interviews.
And the Rams have been looking for an answer offensively to establish who they are all season thus far. At some point before his contract runs its course it's not crazy to think the Rams will find another back who can be the bell cow. Been saying they need that for some time now in fact. I love TG, but this is a tough business it's a damn bummer.
So for myself right now I'm just going to enjoy watching him play when he's in there.
