He played DB at Oregon State and was, IIRC, Lavell Edwards' DC. Robert Anae was Bronco's OC and, we believe more importantly, Jason Beck was Bronco's QB coach. Both are at Syracuse.
Tuttle, Bazelak (Also played at Mizzou, 4* QB) and Gremel (2*)...likely ND won't go after any of them, but interesting one school has 3 QB's in the portal
None of those Indiana QBs are likely to succeed as a starter at the top level of college football.
Brennan Armstrong, on the other hand, was excellent in 2021. Perhaps it was the coaching staff or the personnel around him, but he struggled badly this year though.
Tuttle is the one of the three I'd consider but he isn't very accurate.
Bazelak isn't mobile at all, throws hard but is inaccurate. He has entered the portal twice now.
Gremel started just one game last season, out of absolute necessity because the three quarterbacks in front of him were injured.
ND can find a better option.
