Axe to grind. His statements are crap before he starts.
Objectively speaking, an axe to grind can be as much a motivation to expose the truth as much as it can be to manufacture a lie.
Here's the thing though. He can name names. The allegations don't lend themselves to being proved. How can you prove a hundred dollar handshake even if it happened? Secondly, the NCAA really is only concerned with this stuff if it's pervasive, and the University/Coaching staff has knowledge or reason to know and it turning a blind eye. The only way a program can be held accountable is if they knew, or should have known, and didn't report it. Two prongs: Eligibility and Enforcement. People forget they're two different things. The fact that a huge number of former players are ready to step up and call bullshit on the HBO 4's allegations tends to indicate it's at least not pervasive even if Ramsey and company are being truthful, which, again, doesn't lend itself to being proved.
So, unless Ramsey drops a bombshell about some guy giving him a traceable amount of money, and it can be verified through forensic accounting, or he has some proof that the coaching staff was directly involved in providing benefits, neither of which he's alleged publically...it's much adieu about nothing really. Let him talk. It amounts to throwing a fit for not getting his way.
