Take, for example, last Friday's game between the Winnipeg Blue Bombers and the Toronto Argonauts.
After Winnipeg scored a field goal with six seconds to go in the first half to go up 17-16, Toronto elected to have Winnipeg kick-off to them instead of taking the ball at the 35 and attempting a last second hail mary.
Knowing that Winnipeg was going to squib the kick, the Argonauts special teams coach called for a very bizarre play. Toronto received the kick-off and proceeded to punt the ball right back where it came from. A fortunate bounce allowed the ball to reach the end zone before a Blue Bomber finally pounced on it. After much review and deliberation by the officials, it counted as a single point, and a pretty important single point in the end as the Argonauts went on to win 36-34.
As if that wasn't crazy enough though, it turns out that that was not the goal of the play. If Argonaut special teams players had had a better idea of what was going to happen and had been able to be the first ones to the ball, they would have scored a touchdown.
Another, more famous example of the ingenuity that takes place in the CFL occurred during the 1977 Grey Cup game between the Montreal Alouettes and the Edmonton Eskimos. A combination of melting and refreezing snow led to the field looking more like a hockey rink than a football field.
In the days leading up to the game, both teams tried every type of cleat imaginable in order to try and gain traction on the field. Nothing was working until Alouettes defensive back Tony Proudfoot had the idea of putting staples in the bottom of his cleat. This stroke of genius allowed Montreal to dominate the Eskimos 41-6 and win the Grey Cup.
