You're already rooting against Parrish. Parrish is a CANE.
You can feel free to come in here and remind "y'all" anything you want. You'll just get reminded again that this staff is more than capable of determining who the best backs are and who will get the bulk of the snaps of the committee of backs we have. If that's Parrish and if he happens to be playing "average" as you state, then that just means the other backs are practicing at a level below average and aren't showing they can take Parrish's snaps from him. I don't know why this is so hard for you to comprehend. Over the next few weeks, the staff will determine which backs will be carrying the bulk of the load........and I support them 100% in their evaluations.
Edited to add: This isn't just about running the football. It's understanding the playbook, pass protection, and route running along with running the ball. Whichever backs can be the complete package will get the bulk of the snaps.
