The main points invariably offered to support the hypothesis that Greg doped:
Iron shot
Testing was very poor then
Everyone doping back then
Fastest TT
And that's about it.
If anyone else has any evidence either circumstantial or otherwise, please offer it up.
Because after almost twenty years, to think this is the most anyone can come up with, speaks for itself.
Although a regular forum user, and I think it is Flicker, repeatedly claimed that a former pro who was on the same team as Greg, told him that Greg doped. I have also told this Forum user that his friend is in for a windfall from P.S. because he would be the only former team mate to have seen it.
