Another tough call All three could potentially have a huge season. It really comes down to who you are more comfortable with as a running back. The Eagles will once again rely on Westbrook, but he is getting older. In addition, he could see the defense focus in on him if the passing game struggles.

Addai has the talent but wore down near the end of last season. Dominic Rhodes is back to possibly take some of his carries away, but he should still be the dominant starter in one of the most powerful offenses in the NFL.

Jackson was hurt last year, but he is looking to prove his value this season. If the Rams bounce back enough to give him room to run, he could do some big things. It’s still up in the air whether he will sign a new deal with the Rams or move on when his contract expires, so this season might be a chance for him to turn some heads again and show that he’s still got it.

Overall, I choose Addai. It’s a close one between Westbrook and Addai, but I think Addai has more upside being younger and probably being more of a factor in the offense this year than he was even last year. Westbrook is getting older and could see some carries go to Booker to keep him fresh. None of these are a bad choice in fantasy drafts.
