You remember Game 82 against Winnipeg last season? Both the Flames and the Jets had just clinched a playoff spot, and so, the game was totally meaningless. Healthy scratches abounded, guys who weren't really getting the chance to play in the NHL got huge minutes, and the Flames got smoked 5-1 - but nobody cared, because the standings were set and the goal was more not to get hurt than anything else.
The Flames' game against the Leafs was in a similar vein. It wasn't meaningless, but it did provide serious roster deficiencies unlikely to repeat themselves. The Leafs were depleted from untimely injuries and a Dion Phaneuf trade, while the Flames laid down team law and scratched two big names (and, evidently, struggled at least in part for it).
