Nothing wrong for fans maybe... can turn into plenty wrong for the teams.
1999 in Saskatoon, we played the late "semi-final" against the host Huskies. We end up winning 5-4 in OT, or 2nd OT, I can't remember. Emotional game against the hosts, guy end up going to bed late after eating and stuff (some guys told me they didn't sleep until 2AM because of the excitement). Meanwhile, Alberta cruises to an easy 4-0 win against York in the afternoon game. Guess who was more ready for the final at 2PM the next day?
