I think you are underestimating Wes's pull. He isn't involved with a lot of recruits, but he has a huge influence on a select few of the top recruits. It is also pretty apparent when Wes is involved. Ever wonder why no mid-west school was ever a player for Derrick Rose? Because the Big 10 doesn't do business with him. Izzo, Coach K, Roy Williams none of those guys recruit Wes's kids real hard nor does Wes help them. But when teams like Memphis, Kansas, Oregon, and Kentucky start popping up they all have connections to some extent with him.
What Wes does only effects a handful of players, but as the linked article suggests his influence is strong with a certain group of elite players.
