I don't think what happened deserves a suspension. I'm a law and order type of guy, but this is such an incredibly insignificant indiscretion that I don't think it warrants a suspension. I'm not aware of other coaches suspending players for merely being in a bar underage or for underage drinking. I'm not sure why Blais needs to set a precedent in this case. The only caveat to my position is if Blais knew what was going on and specifically told his players to stay away from there. Then they should be suspended for disregarding their coach's order, but not for the actual indiscretion.
People on this board are coming down harder on the boys than the posters over at POI. I think we all need to lighten up a little.
On a related note, in many Minnesota cities, they are de-criminalizing "crimes" like this and are turning them into administrative citations (like speeding tickets) to make more administrative money for the City rather than having "fines" go to the the State coffers. Hopefully this trend continues.
