Give Saban top 5 classes he dominates, finishes top 5 and wins national title after national title. Give Miles Saban's recruits and he wins a National title. Give Miles his own top 5 classes and he finishes #14 or worse more times than not (6 of the last 8 years).
Miles hasn't done anything recruiting wise that the coach before or after him couldn't do just as well. LSU is gonna get great recruits. Once again I'll bet sight unseen the next coach at LSU recruits as well as or close to what Miles did, and as you can see the LSU coach BEFORE Miles certainly didn't have a problem recruiting to LSU.
