Good point.
I remember writing about him in one of the Lions previews -- think they actually benched George Foster midway through last season to play Scott, who promptly got hurt and ended up on I.R. To be honest, I was surprised nobody else had picked him up ... he's not great, but I didn't think he was overly terrible, either. Just a guy.
And with Peters, Walker, and rookie Demetrius Bell all signed for at least two more years, Scott could potentially replace Kirk Chambers, who will become a free agent at the end of the season.
