I know a lot of people love the recruiting numbers (after all this is a recruiting site) but look at Michigan State. Final Football Polls: They have been ranked in the top ten AP and Coaches 4 of the last 5 years. And in the top 5 three of those five years.
Recruiting: not so much. Going back to 2010 they have NEVER been in the top twenty and three of those years they were not even in the top thirty!!! (They are currently 13 for the first time in forever.)
(*Compare that to Georgia a perennial top ten recruiting power which lags in the final polls....)
I have been saying that Dantonio is the best coach in college football -- he does more with less (if we really believe the recruiting numbers) than anyone in college football.
I think it is all about the coaching. (And some good recruits, don't get me wrong. Also, ND players have a tendency to stay for that 4th or 5th year which increases their star power (if you follow my logic a 5th year lineman who was a 3* might play like a 5* -- is this the case at MSU? (I don't have the numbers.)
Let the discussion begin:
You never got back to me about teams winning a NC without top classes so I found the following information. It kind of goes against your philosophy
The following are the national championship teams from 2001-present and the recruiting classes each program had leading to their titles. Each had at least 1 top 10 class and most had at least a top 5 class. The one notable team was Auburn which still had top 10 classes but a couple top 20 ones as well. I think it goes to show that most teams can get a special QB and they have a shot regardless but of course Auburn had talent around Scam Newton. A couple teams in recent years that were similar are TCU and Oregon which had a great QB but maybe not the best recruiting and won a lot of games, still no championships.
2001 Miami (#2 in 2001, #9 in 2000, #8 in 1999)
2002 Ohio State (#7 in 2002, #4 in 2000, #2 in 1999)
2003
LSU/
USC (LSU #1 class in 2003, #4 in 2001 USC #3 in 2003, #14 in 2000, #21 in 2001)
2004 USC (#3 class in 2003, #1 class in 2004)
2005
Texas (#1 class in 2002, #15 class in 2003 with only 18 recruits, which averaged highest star rating in country, #18 class in 2004 -- only signed 15) If Texas had signed 20 players in either of these classes, they would have ranked in the top five. The #1 class in 2002 was simply too large, with over 30 players).
