If that is the case, I'm curious as to who the other players were and how much was in their samples.
As for the amount reported, it was a "trace amount" in the other 2 samples. If that is indeed the case, it indicates only 3 possibilities:
1) The illegal substance is being used by all 3 players, but only used heavily by Braun,
2) The collector contaminated all 3 sample containers prior to obtaining a sample, AND/OR
3) The collector tampered with all 3 samples, but completely misjudged the amount of substance inserted into Braun's sample.
