We will see what happens. Long ways to go to be projecting that. If things go well, other opportunities will come along for the top assistants. If things don't continue to go well, he might eventually be replaced or IU may not even want him when that time comes.
I know it's tempting to think the 10-0 start will project endlessly into the future but things have a way of changing fairly quickly. No bigger proof of that than IU football over the past year. Hell, much can change for the trajectory of the program, in either direction, in the next week alone. If they get beat at Ohio State the conversation will turn to their schedule and how they have no quality wins and if they deserve to be in over some really good SEC teams. If they win at Ohio State the talk will be if they are the new #1.
Speaking of how things change, I just hope I have a pulse by 2032. LOL ... and ... I remember similar feelings at Purdue when Brohm had major upset wins. Yet IMO there was always an elephant in the room .. Louisville. I not sure any amount of money Purdue offered or would offer to keep him would have made a difference. Based on personal experience growing up I know how much a family is a factor in coaches decisions on to move or stay. Brohm's family wanted to move back to Louisville from articles after the fact of accepting the UL job.
Yes a lot can change. Even with IU increasing the salary pool again for assistant coaches they will be a hot commodity after this season, if their agents are not already approached. As far as the schedule ... non conference was pathetic and just as bad next year. That is from a lifelong IU fan/grad. It's too bad they don't have any control over what the B1G teams they beat do in other games.
If IU looks good vs OSU and loses ... still in playoffs
If IU gets curb stomped at OSU (I don't think they will). .. possibly out of playoffs due to SOS
If IU wins and they could ... OSU might be out and Day might be looking for a new job
Not part of this thread but I have to say when I saw the background of Coach Walters I was having big Tom Allen flashbacks when hired as HC at IU. Very similar backgrounds in coach, not playing ... but IMO he wasn't going to get the job done.
