I think we can assume Lacy and Franklin are locks for the final roster which is while I find the RB battle for the other one or two spots so interesting.
I still think Starks has shown the best stuff of the rest but he can't stay healthy which is a huge negative and if he gets injured again he'll be gone. He might have to prove he's the #1 RB to stay which might be very tough.
Green has/had all the physical tools, but clearly didn't know how to read blocking nor did he have the patients to wait for a hole to develop which are huge problems. He's gotten some what better with his patients but still struggles to read the blocking and has a couple physical injuries and some problems with his knee. Based on what he has said the knee shouldn't be a problem no more.... if it is he could be gone just like Starks. But if he's healthy do you might roll the dice and get him another year to see if all that talent might finally boom.
IMO, Harris isn't flashy at all.... but for the most part he gets the job done and that's what you need. He's a north and south runner, which I love, he has some speed and is able to get into small holes and get up and go... which is very nice and pretty good at reading his blocks.
Pease, I think at the end of the day the Packers will want to keep him on the 53 man roster.... but there just won't be enough room unless he can help out a good bit on STs.
