You're right about the likelihood of success with 4* guys. But when an LDS guy is also a 4* we need to be all-in to get him. Hammond had coaches flying in from Tennessee, Texas Tech, and even College Station (Jimbo Fisher in a Helicopter) while BYU ghosted him for 10 months after doing a uniform photo shoot after he won MVP at the Provo camp.
BYU's QB recruiting lacks energy, commitment, and desire. How do you end up with a team with half the guys on the team from a 50-mile radius of your stadium? Laziness. How do you end up with a team that has the same last names on jerseys generation after generation? Nepotism and laziness.
Football recruiting needs to look a little more like basketball recruiting is starting to.
