It seems the real proof will be next year. If he makes it all the way back we have several choices that lend to redshirting LL, and then it seems a battle for 133 several years down the road. Nagao might even be a 141 two years from now. Robbie with his experience, fully healthy, and a fire in his belly could be our best multi year option. I think all here hope he makes it all the way back so we can find out.
No doubt the deck is stacked against him a bit with not only the inbound talent, but the tall task of getting back both his confidence and his game. Assuming he can do so, there is then the always unsettling reality that shoulders injured multiple times seem to be ticking time bombs.
