I will pass. His good days this year were against almost entirely bad, bad run defenses and he just has age and growing injury issues going.
I normally don't look at injuries and say "injury prone" or likely to get injured but this guy is Eddie George: just a clear history of excessive wear and tear that is catching up to him.
He will have those nice days (but not dominant ones) next year but he is probably also going to miss some time and it will likely be I. Critical weeks that will crush you. I think there is a point where, if you draft old RBs that can't be something special anymore, you set yourself up for misery. Sjax on a healthy falcons team is option 2.b at best. I would take a fjax over him for much cheaper and I bet you get as good or better results
I agree he won't be dominant but frankly he really never was because he never put up big TD totals (other than 2006). He has just been a very consistent solid top 10-15 guy on some terrible teams. The line needs upgrades and to get healthy. I view the 2b as a positive when Julio and roddy are both healthy it should open things up for him.
As for Fjax his ADP was late 9th round this year being drafted primarily as a handcuff. He significantly outperformed spiller (top 15 RB) on similar touches. I expect drafters to draft him as a low RB2/high RB3 with handcuff potential and probably have an ADP in the 6th round (can't be much lower than that given this year can it?). So that said would you rather have a guy who will carry the majority of the load or the timeshare split guy that will likely be out touched next year if spiller is healthy with relatively similar ADP? Maybe I'm in the minority but I just can't see Fjax duplicating (or coming within 80%) of next years stats. This was a top 5 of all time performance for a 32 year old.
