That's the honest truth. Many of them won't be good enough, which simply comes down to the fact that making the NFL is so hard and such a low percentage.
But if you're a talented 3,4,5* player coming out of high school, then chances are you think you have at least some shot to go to the NFL. So BYU needs to start getting more kids drafted because it does matter to recruits. We shouldn't target too many kids that don't believe on some level that they're a potential NFL player because that most likely means they weren't good enough in high school to stand out.
