Cowan didn't get off a plane and get to the dome on game day. He came in on Tuesday night and the team had a game day skate yesterday morning. Granted, it's not the same as having a few full practices together but it was at least a start.
I chalk it up to the day after a very emotional 24 hours, the slight time difference and perhaps the change in altitude....I thought he got a little stronger as the game wore on. As with all things, time will tell and who knows, maybe Kisio still has a deal or two up his sleeve.
