This leads me to the question the statement, "is everyone at this level doping?"
If so, then were (are) NCAA champs who have proven they can run with the best, ie Murphy, Brazier, Engels, Hoppel, doping? I find it hard to believe these guys were doping in college and into now. I thought the consensus on if guys doped in college was.. probably not.
Furthermore, someone like Clayton who ran his 800m PR shortly after his NCAA champs and prior to joining NOP, I just don't think he's dirty. Same kind of situation with Brazier, Hoppel, Engels in their own ways.
Maybe I'm too optimistic, but idk.
