I remember some years back how Texas was going through a heat wave of sorts, it was Hot even for Texas, towards the start of the season.
The eagles were going to come to play at texas stadium and everyone was saying how the Cowboys would have the advantage because they had been working out in Texas and the Eagles would be the ones to struggle...well that turned out to be the direct opposite as many cowboys players were having trouble and the eagles won the game easily because they prepared.
This whole thing about weather normally makes no difference at all...especially in the playoffs this time of year because more often than not there will be some games in the cold.
The weather is not the area we should be thinking about....we need think about Our Defense going against their Offense and Our offense against their Defense.
