The 2 ways to have a championship caliber team are 1. Have the most talent with steady QB play (see Bama and UGA recently) or 2. Have ~top 10 talent and elite QB play (See Clemson & LSU recently). Unless ND is able to sign consistent top 5 classes, elite QB play will be the mostly likely way ND wins a championship.
A guy like Angeli basically has a similar ceiling to Ian Book, which isn’t goin to get you over the hump if you aren’t signing consecutive top 5 classes. After 5 consecutive 10 win seasons, it’s fair for ND fans to target what is needed to get the program to the next level.
IMO you need to sign a top 15 QB even in years after a 5 star. Hit rate on elite qb prospects is too low to take an “off year” on a safe kid with limited upside. Angeli was really like the ~40th best QB in the class if you look at just Rivals and 247. ESPN pumped up his ranking because he was in the UA game, skewing the composite.
