Recruiting class rankings

Is there really a purpose in ranking or grading a recruiting class? To me it is almost like preseason polls. Pointless! It makes for good debating and discussion but how often do most of these recruits pan out to where the "experts" say they should? I have to admit i get excited when i see that the Hokies get commitments from 4-star athletes but we have a tradition of pulling in the "nobodys" and producing with them. I like at the board for next season and i can't help but wonder if we aren't better off without some of the 4 and 5-star guys. Look at Miami and FSU. They get the big recrutis consistently and what do they have to show for it? Maybe you can blame it on coaching, Miami, but some of it is just the simple fact good in high school does not equal good in college, FSU. Give me a guy with heart and drive and the ability to be coached over a guy with a quick 40 time anyday!
