re: What do the LSU coaches think of Nussmeier’s potential?

I get it. We haven’t seen a TON of snaps from Nuss. But I feel like the answer to your question is VERY obvious.. Nuss will start next year.
Look at what JD5 turned out to be. And remember that Nuss battled him ALL off season for the starting role.
And then add that to the snaps that we HAVE seen from Nuss..
Obviously there is only one JD5 in LSU history. And he FAR exceeded expectations.
But I think it’s safe to expect a VERY explosive offense next year. Nuss’s arm is beyond special. If he’s accurate with the ball and can half arse read a defense he will be just fine.. especially given he will have a HELL of a OL, a great stable of backs and a great WR lineup to work with.
