A couple of things to consider though, that might bode well for Todd:
1) In contrast to last season, nobody can say he was overworked this year. And last season followed a previous season where he was the centerpiece of the offense.
2) While we would all have preferred to see the Rams make the playoffs, the fact that their offseason - and TODD's offseason - starts now gives him a lot of extra rest relative to last year.
So with less accumulated wear and tear on him and extra rest time, if there truly is something left then he could potentially come back next season rejuvenated and ready to roll.
