I think Gus can be good, but based on what he has shown the past 2 seasons, he's a solid starter at best. Will probably get 4+ ypc, but wont do too much special except for a big play every once in a blue moon.
I definitely think Yearby has shown more and has more potential. I think Gus will be very solid this year, but he still has a lot to PROVE. At this point we're basically just hoping he's gunna come in a be a mini beast mode, when he hasnt shown he can do that almost at all. Based on last year, Yearby should definitely be the starter.
We'll see how this summer practices play out though, I'm hoping Gray does well too, and we are able to redshirt Walton still. I feel good having Yearby, Gus, and Chocolate to replace Duke, I'm just not so confident they'll be used the proper way...
