I will be surprised if the Clemson running back makes the team, but the beauty of this is we will see on the field.
RB tends to be a plug and play a little. With that being said, I don't think Blue will be ready for a big role this year. If things go well and he looks the part, I think next year is when you may see him a part of a tandem.
The big concern is who takes advantage of those carries. Sanders and Williams have proved anything but that the last two years. The Cowboys better hope the past two years were the exceptions and they still have something left in the tank. At the RB position, that doesn't happen much.
I am a Deuce fan, but I can count on him to produce or even make the team.
I don't see a lot there at RB. Maybe some enticing long term play in Blue, but this year looks rough at RB if that is who they go into the season with.
