It's not that he transferred. It's how he did it.
In my opinion, he would have been a better team this year had he stayed. He would have improved, as players do, and would have given us a better record. That's all speculation, of course. I don't know why he left. It all seemed childish and strange. But what are you gonna do.
I've heard so many times that SS (and Mason, by the way) aren't NFL QBs. That's speculation too. You never know how well a college QB can improve to play in the pros (Jalen Hurts) or keep working and find themselves in a position to play (Mason Rudolph). I think SS had a chance.
