Obviously any comparison won't be exactly the same.
Point #1 ... possibly but CFB is not the NFL where rosters stay more consistent.
I disagree with your point #2, at least in BYU's first year. BYU had the #11 ranked SOS. utah's was ranked in the 40s their first 2 yrs and top 10 their 3rd year only.
Disagree somewhat with point #3 too. The transfer portal cuts both ways so you can't just state that it makes improving easier.
I've never said Kalani hasn't made mistakes especially with his coaching staff. I was one if the first to call for him to replace Tuiaki.
Difference now is that he has finally replaced him and looks to have a strong staff finally. Let's not call for his head until we see what they can do together. All we need is to start over again.
