There are 20 spots of difference between Boise State and Colorado in the post you quoted. By your logic, why wouldn't Colorado have had EVEN MORE success than Boise State if the conferences were switched? If Alabama jumping from the high teens to the low twenties is a monumental leap forward, and Colorado had a 20 spot edge on Boise State during your average recruiting year, then logically you SHOULD expect to have had EVEN MORE success than Boise State had were the positions reversed and a far better team.
Which begs the question, of course, why aren't teams trying to move down to the soft, cushy conferences if it is so darned easy?
I accept the basic importance of recruiting rankings as being a RELATIVE indicator of talent. What I'm arguing is that these indicators are MUCH more accurate at the extremes than in the fuzzy middle. I would state, and I hope not to offend here, that Boise State had far more talent on their team during that 2006 to the present time period that we're discussing than Colorado did despite the 20 spot difference in recruiting rankings.
Let's say you're looking at 10,000 players. Of those 10,000, one hundred are CLEARLY elite. They are so far better than the rest that it's easy to say that they're going to be studs with a high degree of accuracy. 6000 are clearly worthless and just aren't good enough to play at the next level. You can say that with a high degree of accuracy. That leaves 3900 players that are a little harder to figure out. You assign them relative rankings but they may be heavily error prone.
You guys had the better coaching staff in that timeframe, so no, I should not logically expect EVEN MORE success than Boise in that timeframe. Unless you are now mixing up arguments and trying to say talent is all that matters and coaching is secondary.
The difference between 50 and 70 is nothing compared to the difference between 20 and 1. This is where playing some of these teams regularly ranked in the recruiting top 10 every single year becomes a factor. I have seen plenty of teams with top 5 recruiting classes in person. I have also seen plenty of teams ranked in the 20-25 range over the years as well.
In 2005 (the last winning season for the Buffs), we played several pretty good teams. Teams like Oklahoma State, Texas A&M, and Missouri had multiple recruiting classes leading up to that season ranked in the top 20-30. We absolutely crushed them, all three of them. Unfortunately for us, we also had to face a Texas team that had several key contributors from a 2002 recruiting class ranked #1. They destroyed us twice that season and won the national championship.
