The sample size for Cam is still small (90 total rushes and 13 receptions over seven games, of which he was minimally involved in two of them), but it is starting to add up to something meaningful. The 2.43 yards per carry average is bad no matter how you present it, and of his reception yards (104), 40 came on that trick play throw from OBJ. Take that out and it's 12 catches for 64 yards - 5.33 per reception - also not acceptable.
I have my fingers crossed that he is still working his way back from the Achilles injury, and that we will see a return of his burst, but time is beginning to run out for him to show it. Achilles injuries are often a career ender. Sometimes it means the RB never comes back, and sometimes he comes back and he isn't the same. I am ok to give him a few more games to see if it happens, but ... the clock is definitely ticking on his once VERY promising career.
