Here is a FootballDocs article about the 'two year rule' with RBs and ACL injury.
Every case is different but if you can ride out a potentially below average year from Deuce next year, he may
return to form the following year and I think he is worth the chance.
One thing the article doesn't take into consideration, which I think is a major factor is age. Jamal, Edge and Deuce are all roughly the same age but Jamal and Edge suffered their injuries early in their career on relatively fresh legs. Deuce is over 1000 carries for his career while Jamal and Edge had only 1 and 2.5 years under their respective belts.
I don't think Deuce is done but it will likely be a tougher road back. I would probably not draft Deuce in the 1st or 2nd next year, but I'll take him if he falls to me in the third.
