The injury set him back. He also was never featured so that he could get a lot of reps and develop. We had good talent at the position anyway without any drop off between the top 3 backs we had. It was a classic case of locals being favored over outsiders (which is what we should do considering how bad we are at recruiting in our backyard).
There's definite local favoritism among the fanbase - which makes sense. But the coaches also play favorites sometimes. It happens.
Gus was a victim of both here and it created some false narratives. But the transfer on his part was smart move and it's worked out great for him.
