So far it's mostly just (BYU) people saying that he could potentially be a candidate, but that they don't want him to be. Nothing really substantive at this point

Given the timeline, I think it's highly likely they go through this season with an interim head coach and make a call after the season.

At that point? Who knows?

I know a lot here don't think Jay Hill would leave BYU for USU, but a lot depends on things we simply don't and can't know.

There's a bunch of hypothetical reasons he could choose to take the job:

• He may have found (purely hypothetical, just as an example) that he prefers to control of being a HC more than being a coordinator.
• After a rough 2024 season, he could be worried that Kalani is on the hot seat and his job security is in danger (this is likely at least partly why Burgess moved back to BYU)
• Or after a surprisingly strong 2024 season and another big long extension for Kalani, he could see his path blocked at both BYU and Utah (Scalley), and figure USU is the best in-state option available

Of course those aren't the only hypotheticals, just some that would point to taking that job. Here's some others

• After a rough 2024 season (mostly due to offense), Kalani is on the hot seat and Jay Hill is seen as the likely replacement if BYU doesn't fix things
• After a rough 2024 season (including the defense), USU isn't as interested in Jay Hill as they might have been now

And that's just considering the USU head coach role. We haven't even gotten into the possibility of Whittingham retiring, Scalley taking over up there and Utah coming after Hill as DC. I don't think they would, likely would tab Shah or Swan instead, but it's another possibility that could throw a wrench in it 

Bottom line, nothing is happening until after this season anyway, and what happens this season will impact all those decisions, so it's simply too early to worry about it
