Yep, I had him back in 2005 for a class. Guy literally spent about 4 or 5 classes talking about steroids in baseball. One specific time we had a class discussion on it, and about 6 or 7 students kept naming batters, and I'll never forget when he said something along the lines of "Pitchers take PEDs as much as hitters, if not more."
So surreal looking back on it. He also took phone calls from Clemens a few times during class and just left us sitting there for ~10 minutes or so. Talked alot about his time with Toronto/NYY when he was Clemens and Pettitte's trainer.
