Tornado....I respect your opinion, and I'm certainly willing to engage in a mutually respectful discussion.
In full disclosure I was part of Dewey's 93 team and that had several of us out drinking during a conference weekend against ISU where we were suspended afterwards. Closing Sullys was a fairly regular occurrence (You can insert joke about baseball players not being athletes if you wish

)
Dewey always told us he would give us enough rope to hang ourselves with....and that rope got a lot shorter for the remainder of the season. It also galvanized us where we swept Creighton the next weekend. And although the punishment was handled internally it made the newspapers the next day. Some may say that loss to ISU on Sunday kept us from getting an NCAA bid (We ended up 40-16)....but in truth it was probably a midweek loss to Illinois Weslyan that sealed our fate more than that conference game.
Now there were no laws broken in the incident above. Maybe university rules as a whole were different back them....I'm just sharing my personal experience. Were there athletes drinking. There were. Were there athletes not drinking....sure there were. I was pretty straight and narrow in high school and if the current rules were in place in 25 years ago (ouch, it hurts to say that) then maybe my social life at BU would have had a minimum of alcohol consumption. Who knows?
