How did Travis Tygert build the case against Lance? In part, by getting people who had heard and seen - and yes maybe participated - in suspicious or illegal conduct to cooperate. Having conducted many criminal and civil investigations, this is how you build a case - you get info from lower level folks, then gradually work up the chain to your target.
This really isn't anything like lance. For lance they for people who had dope with lance to testify and getting reduced bans etc. Or getting bans to start at a convienent time.
most often stuff against NOP is second hand or smoke that might mean fire. Testing on his son I could see either as paranoia or investigation to dope. It seems they might have pushed thyroid stuff but you don't need aTUE and it isn't banned. The stuff about wanting a test for Rupp was explained, made complete sense and the governing bodies were in the loop so that doesn't even seem to be an issue.
