It's hard to envision a scenario where Gus and Yearby are both at UM next year. Pretty much counting on Gray being gone.
As stupid as it sounds, I don't see it being too farfetched for Yearby to enter the draft. He'll be behind Walton next year anyway. His draft stock isn't going to get any higher, the only way it can go is down due to getting beat out by Homer, Edwards, McFarland, or whatever or a serious injury. He's got a 1000 yard season on his resume, 2 other solid seasons and more than 2000 yards on his career. Solid pass catcher, pass blocker (except 1 play this year he let Kaaya get blown up).
Add in the fact that he has 2 kids. He'll never be an NFL starter but he could have a role on an NFL team. 3rd down scat back with wiggle and pass catching ability. Just being on a roster is over 500k... Might be the smart move for him tbh.
