On Dec. 3, 2007, John Hufnagel was introduced as the new head coach and general manager of the Calgary Stampeders.

Just 15 days later, Marc Trestman was named the new head coach of the Montreal Alouettes.

Since those hirings a little more than two weeks apart, the Stampeders and Alouettes have been the class of the Canadian Football League. Each team has won a Grey Cup championship — coincidentally, the Stamps won theirs in Montreal in 2008 while the Als claimed their title at Calgary McMahon’s Stadium in 2009 — and each club currently occupies first place in its respective division with matching 9-3 records two-thirds of the way through the 2010 campaign.

That background makes Friday’s tilt at McMahon between Calgary and Montreal — not to mention the follow-up contest at Percival Molson Stadium — slightly more intriguing than the average inter-divisional clash.

The Stampeders and Alouettes have met five times in the Hufnagel-Trestman era, with Calgary holding a 3-2 advantage including the victory in the 2008 Grey Cup at Montreal’s Olympic Stadium.

Overall, the Als have the best record in the CFL since the start of the 2008 campaign with 35 wins and 13 losses. The Stamps are next best at 32-15-1. Both Calgary and Montreal boast 3-1 post-season records under their current skippers.
