Marlin Mack

Sad to say because I like Mack, but would be a "no" for me at this point. RBs typically suffer the most (along with LBs) from Achilles injuries:

Here's the conclusion if you don't want to read the whole thing:

Conclusion: Following Achilles tendon repair, less than 75% of players returned to the NFL. Postoperative career length was 1 season shorter than matched controls. No difference was observed in the number of games per season played compared to matched controls. Postoperative performance scores were significantly worse for RBs and LBs compared to preoperative and LBs had significantly worse postoperative performance when compared to matched controls.

So, basically, Achilles tendon tears typically take a year off a player's postoperative career, and RBs "postoperative performance scores" were significantly worse than other positions.
