The things Graham have on his side is that he's only been in the league 7 years and he's never been an every down back so he still has some tread left. The latter reason I guess could also be a negative since we have no real experience to gauge what he may possibly be able (or not able) to accomplish. I'd say though that with the high number of targets he gets out of the backfield plus a semi-full load of carries he should be able to put up at least 100 yards and possibly a td.
Forgot he had started in 13 games in '07 after Caddy got hurt which he rushed for 898 yrds and 10 tds. He did fairly well though we are 4 years removed from then.
