Do not want to create a new thread, but it appears the RB to replace Ball* has been on the team since last season. Deltron Sands, former 3* recruit out of STA and Oregon State, is now listed on the roster. He was one of 4 freshman not to get redshirted for Oregon State his first and only year there before going down with an injury. Ended up being dismissed from the program for unspecified reasons. He will be either a RFr. or RSoph. as the article posted states Oregon State was going to try to get a medical redshirt for him. My guess is that he will be a RSoph. He looks like the front runner if no Ball. With Ball, a big upgrade at 3rd down/speed back.
*If the med redshirt does not get approved.
