We have zero idea if Fox, Ihnen, Betts or Christie will be more effective than TT. Are they healthy? Do they get too nervous? Do we utilize their strengths to make them look good? Betts played at a small high school, came a year early, he could be best player on the team or never leave the bench. Christie couldn't carry his high school team...seems unlikely he leads the Gophers out of the darkness.
We need a coach with the stature and ability to get 5 to 7 guys out of the portal and put a team together like Iowa St, Kansas St, Pitt, Missouri, Texas Tech last year...lots of examples. One year is enough in 2023 with the portal if you can coach.
