Stars do matter, but so does coaching, and you need those role guys.
Someone did a breakdown awhile back about past classes and the results, it was really interesting. You really have to have some of those elite guys(hubbs, stokes) but unless you're Kentucky, you also need those 3 stars who will stay four years. I did my own comparison last year of Tennessee and Michigan states roster...our players had the EXACT same average star ranking as Michigan State...yet people whine when we sign a 3*. It was just nice to show Michigan state has them too...with the right blend and coaching it doesn't matter...like I said unless you're Kentucky recent history has shown you need some 5*, 4* and even 3* in your rotation.
