The term 4 star gets thrown around a lot. I think it is valuable to look at multiple recruiting sites to get a sense of what kind of talent we actually have. When you do that you will find that Bronco has recruited only 10 guys in 10 years that are 4 star on multiple sites.
Of course we know 2 or 3 star players can be excellent. We know that these services aren't perfect. But the fact that Bronco has had only 4 "obvious to everybody" 4 star players play through their senior year shows that Bronco hasn't had much in the way of elite talent to mold.
