Do you know that each year there are only 30 recruits rated at 5* across all positions, offensive and defensive? Most of the recruits that people **** and moan about are 5* or border-line 5* (they don't get the fifth because it's a numbers game). Not only are they good but they have ideal traits that scouts look for like size, speed, drive, etc. Do they bust, yes, but most of those types are going to be highly drafted no matter who coaches them based on their own natural growth and future potential.
Someone that's a good or great coach takes someone with less than ideal traits and gets them to perform above what their potential would indicate … repeatedly. Now look at the people we've had drafted recently. Have any of them come in with ideal traits that indicate they were not properly coach or developed? The ones that stand out to me are Chad Thomas, Chickillo and Navaugh Donaldson (although he hasn't been drafted yet). None of them are CBs.
