TJ's old samples tested negative for EPO, which is why his victories over Garbrandt weren't overturned. TJ isn't alone in his PED use. Silva, Jones, and many others have been caught using, but they don't receive a fraction of the hate that TJ gets. Silva has his excuses (and they changed quite frequently), but so did TJ--that horrendous, horribly advised weight cut.
Team Alpha Male released footage of Garbrandt knocking TJ down during training, edited the footage, and called it a knockout. Chris Holdsworth concocted the story about TJ right at the time TJ was to fight Garbrandt for the first time, playing mind games with TJ. I have very little sympathy for anyone at TAM--and Garbrandt, in accusing TJ of using EPO, indicted TAM at the same time.
Renan Barao's corner said that TJ had "pillow fists" and "Barbie doll hands" (or something to that effect). And that was AFTER being knocked out by TJ once already. I'm shedding no tears for Barao.
TJ cheated, plain and simple. It's not up for us to forgive, but we should at least be consistent and hold others to the same standards.
