Very rarely do coaches pay any attention to the "stars" made by recruiting sites (fans shouldn't care either). If you following recruiting nationally long enough only those that are in extreme hotbed areas of talent like the South, Texas or California pay attention to stars. I've seen Ole Miss and USC staffs allude to it but majority of the time most coaching staffs pay no attention to them. Most of them that don't pay attention are coaching in regions were there is either one of two things happening... not a huge abundance of regional talent and they know their schools don't get the "bumps" by the recruiting services when a kid commit to them. They just worry about finding the best possible talent that fits what they are looking for on and off the field. Work ethic and character are the two biggest. We should know better that there has been soooo many "lower rated" star kids perform at a 4-5* level in college.
Good post. I tend to look at stars like this. The higher the star rating the quicker the recruit can help your team. 5 stars, higher 4s can come in and contribute very early. 3 stars will probably need atleast a redsirt year and another year or two to develop into a 4, 5 star talent. Just because they have 3 stars doesn't mean much to me, only that they aren't fully developed yet and will need a few years to see the field.
That's why most 5 stars are men amongst boys, they just developed physically earlier then 99% of other kids their age. It's up to the coaches to spot talent and project just how big these kids are going to be 2 or 3 years down the road.
This is why Bo's first two classes are killing us now. The DL guys we got were flops, and we can't get the 5 star play early kids. The last couple classes need time to develop, we need Kevin Williams to be healthy this year for any shot at being decent on the dline.
