Interesting stuff. The popular idea among any college team's fans is "If we win more, we'll recruit better" and that's true...to an extent. You kind of have to win at a decent (9+ wins) level if you want to pull top 10 classes. But winning at that same level doesn't necessarily mean you will automatically recruit at a top 10 level. Look at gator tears and laugh at how their fans can't fathom how their team can manage to win 10 games and still get out recruited by "lesser" programs.
On the opposite side of the spectrum is the group of fans who disregard winning and say "coach X is just a great recruiter and he can pull top classes whether the program is winning or not". That's not true either. As the article mentions, it's incredibly rare for a coach to recruit at a very high level if his program isn't winning big...unless he's still in the fist year or two of his tenure where the "honeymoon period" isn't quite over yet. If a guy is in year 4 or 5 and he's only winning 6 or 7 games a year, it's almost impossible for him to pull a top recruiting class. It pretty much never happens outside of a few very rare occasions.
Bottom line is, no matter how good of a recruiter you are, you're not going to be able to consistently convince top classes to sign if you're not winning games at a reasonably high rate. At the same time, just because you're winning games, doesn't mean you're going to sign top classes. Especially if your coach is a cousin Eddie lookin' doofus who's wife sexually molests players.
