Well, since the suspensions are based on University policies, not NCAA rules violations, your claims of UF "cheating" are completely baseless.
That said, Thomas served a 1 game suspension at the beginning of the year for testing positive. As is the case with the policies at both UF and UT, he is suspended indefinitely for his second offense.
He is appealing the suspension by stating that the 2nd test followed his first test too closely and is the result of the same incident. Since the THC that they test for is fat soluable and stays in the system of an average person for 30 days, it could easily be longer for a guy Thomas' size (he carries a fair bit of body fat). I'm sure there will be some analysis performed to determine how high the levels were at the time of the 2nd test to see if it corroborates his story.
If it does, he could be allowed to return to play quickly. If it does not, I'm guessing that he'll get several game's suspension.
When you look at both the UT and UF policy of allowing an "indefinite suspension" for the 2nd offense, it's really providing a lot of latitude to the decision-maker. That's not necessarily a bad thing since each case is different, but I would think that a person who fessed up and came clean would be given a shorter suspension than a guy who claimed he didn't use the drugs a second time and then have tests prove that he did.
Either way, since it's not an NCAA violation that we're talking about, and the player wasn't taking a performance-enhancing drug, there was no competitive advantage gained for UF.
Frankly I think you're just looking for something else to whine about. UT's lines got beat in the trenches. 95% of the folks here accept that and move on. Perhaps the thread starter here should do the same.
