So, if I'm reading that right, there is more correlation to recruiting in the same year than in previous years. Thus, would tend to show that success affects recruiting (more correlation in the same year, whose recruits have nothing to do with that year's on-field success) more than recruiting affects success (less correlation in previous years who's recruits are directly responsible for on-field success). Would that be correct (condeding your first two sentenses)?
Missed this question.
I don't think success affects recruiting more than recruiting affects success, because the correlations for recruiting rank in 2009 and 2010 (with a majority of those players seeing the field) are still pretty strong [depending on your discipline], and the difference between those correlations aren't quite statistically significant. Rather, I think that it's a virtuous cycle: for the most part, if you recruit well, you play well. If you play well, you recruit well.
I was doing some research for a slightly different question and found some interesting tidbits. I was looking at how the recruiting classes compared in the B1G since 2008 - including Nebraska over that time even though we obviously weren't in the conference the entire time. I used Rivals team rankings.
- Michigan had been #2 each year except for #3 in 2011. They fell to #4 this year.
- Nebraska had been #3-2-3-3 the previous four years until falling to #5 this year.
- Michigan State had been #5 for the previous four years before jumping to #2 this year.
- Minnesota has been #12 the previous two years but moved up to #8 this year.
- The other schools were either similar or all over the board.
There is nothing definitive about that and it is a small sample size but that is a noticeable (if unscientific) correlation indicating that recruiting improves when you do well on the field and declines when you don't. There was really no indication in recruiting that Michigan St. would suddenly be a Top 5 (in the country) team, definitely no indication that Wisconsin should have gone to the previous three Rose Bowls (they were #6-8-11-7-8 in recruiting in the conference from 08-12) or that Ohio State should have fallen on their face a couple years ago (they are basically #1 every year).
I'm not trying to make the case that recruiting doesn't matter - it definitely does. I just think that it tends to follow success rather than lead it. You happen to find a few gems in recruiting, get a couple breaks, win a few extra games and you start to get some better recruits and the process snowballs.
