Well the Grey Cup was terrible for me as a Stamps fan! Like Mattiuek said, the Western Final was far more entertaining.
The CFL is a pretty good league. In recent years it has had some very good players who have gone on to do well in the NFL, most notably Cameron Wake. NFL teams are watching for players here, which makes it an attractive place to play for a player who still wants to make the NFL.
It is a very different game though as everything is geared towards offense, such as field size, scoring system, only needing one foot in bounds as a receiver etc. It makes for an entertaining game.
