There are whispers of the identity of the possible culprit, ranging from the ACC to the SEC. One message board (yes, not entirely credible) claims the complaint was reported to the ACC, then to the SEC, then to the NCAA. If true, look at either Florida State or Clemson. Miller was a one-time FSU commitment. Former Tennessee coach Eddie Gran just jumped ship to the Seminoles. Clemson is feasible because it's a South Carolina school that lost out on the two biggest prospects of the state aside from Kelcy Quarles.
Should the complaint have originated in the SEC, look at the Gamecocks' Steve Spurrier to be the snitch. USC leads for Lattimore's services, who just so happens to be the key contributor to the NY Times' story. Spurrier has had a vendetta against Tennessee since the Johnson City product was spurned by the Big Orange in the 60s or 70s. His hatred is well documented. As is ours for him: I admit I was one of several fans leading a chorus of "Pump Our Gas" above the USC tunnel as Spurrier and Co. left the field this past Halloween.
It wouldn't surprise me if every coach in the SEC joined in USC's accusations. No one likes Lane Kiffin. As they shouldn't. He's ruffled feathers from day one. But he's not being paid to make friends. This isn't the good ol' boy network of the 90s. It's big time College Football. It's a business. Lane is looking to win championships and make money, not buddies. One thing the opposition forgot about, though, is that Lane Kiffin is one brass, crafty SOB. Should the source ever be leaked, does anyone really think Kiffin isn't the type of person to hire an assistant just to dig up the corruption at other schools?
As we learned in middle school, snitches get stitches. We've seen the snitch. Expect the stitch.
