To win a Championship, you basically have to have a D of future NFLers backed up by a majority of future NFLers, especially along the DL
Clemson, for example, has 3-4 guys on their defensive front that will be on NFL rosters next year backed up by at least 2 guys that look to have the NFL in their future. One being a freshman all American last year. AND Clemson isn't even picked to win their conference. NOR are they ranked in the pre season top 20.
