There is no doubt that on any given afternoon a team of 2 and 3 star players of high character with the proper motivation and a good, intelligent gameplan can defeat a team of 4 and 5 star players. Thats been proven time and again (Utah over Bama, Wake Forest's few 9-3 type years, Navy's recent success just to name a few) However in a 12 game season, especially in the SEC, you'll never have enough wins tallied at the end to compete for a NC with that type of team.
That being said, I don't think thats what he's trying to build. He wants a good mix of both. And the assumption that all 4 and 5 star guys are self centered thugs any more than 3 star guys are is a complete fallacy. For every Nukeese (thug) or Kelly Washington (Me First) type there is a Tebow (high morals), Al Wilson (team first) or Eric Berry (whole package) type out there amongst the 5 stars. The key is to get the high character AND high talent guys. There are plenty out there, we just haven't done a good job of landing those guys in the last 7 or 8 years or so. Thats what DD is trying to do. Only time will tell...
