The Grey Cup is the most prestigeous trophy of Canadian Football.
Saskatchewan was leading all through the game by a substantial margin only to have Montral come back to win 28 to 27. The second last play Saskatchewan had too many players on the field and got penalized giving Montreal a second chance for the botched field goal and their winning field goal gave them a one point lead and the cup.

It was interesting to watch the Saskatchewan fan go from glee to worry to disgust and the Montral fan go from small cheers at small gains to utter joy.
I took these casual shots for the expressions and are by no means to be photographic works, but fun in watching people as fans.
