he'll be very injured for us probably
the last time he played more than 30 games in a season was 12/13 (33 games), 5 years ago. all the other seasons he usually plays around 20-30 games per season, while our starters play ~45-55 games in a season. even if we trusted his quality (and you shouldn't, not for a player that's injured as much as he is), he probably couldn't handle the starting RB role due to his fitness issues.
