Among all the injury reports this weekend, undoubtedly the most interesting thing is that Lewis is out with an apparent hamstring injury. Those type of injuries definitely linger, so this might be one of the first of many signals pointing to the emergence of Jerome Harrison or James Davis. Davis is a rookie so I expect Harrison to get more carries, and eventually become the starter. So, before you do anything else, go pick up Harrison.
You may not want to play him @BAL this week because he'll probably get 15 carries for 60 yards or something but he'll probably emerge as a flex starter or even RB2. Harrison averaged an eye-popping 7.2 ypc last year even if it was only on 34 carries. He definitely has the potential to be fantasy relevant when given the chance.
