I am not a Coach Cal fan. In fact I despise him. However I dont think he uses ranking services to evaluate his own recruits. He and other coaches make a lot of cash and one reason is they can evaluate thier own talent. It may usually match up but not always.That sounds like something a Kentucky fan would say to rationalize their position, or as an excuse if he goes somewhere else. A top-30 player may not be the headline to their class, but it's still borderline burger boy. Their current class has 4 guys ranked 30 or lower, and it's #1 in the nation by 247sports.
I think BU can evaluate talent and sees more of Curbelo for example than others may. I dont think player rankings really mean much to coaches vs thier own assessment.
Someone ranked at 40 by a service may and could be in Cals top 10. I think he usually gets who he wants and is a snake in my eyes for how he does so everywhere he has been.
