As the teams take the field for pregame warmups, here are a few observations from University of Phoenix Stadium in Glendale, Ariz.

Is there anything funnier than a snow angel being flagged for unsportsmanlike conduct? By the way, that’s the craziest thing I’ve ever seen from the very businesslike Wes Welker. Snow brings the kid out in everyone.

The Patriots are 9-0 all-time in snow games at Gillette Stadium. Mike Vrabel is clearly fired up to play in the snow. He was the first player on the field today, running back and forth in the snow to check the footing on the field. He was responsible for getting the Cardinals off the field on their first possession, tackling Tim Hightower for a loss.

An interesting note on the Cardinals running game, which is currently ranked dead last in the league: Without J.J. Arrington in the mix today (knee injury), we may see some more of Edgerrin James. If you haven’t been following his travails, he was benched in the seventh game of the season and replaced by Tim Hightower, and since then he has just seven carries for 15 yards. If you want an unlikely hero in this game, he’d be it. James has averaged 105.6 rushing yards per game in the nine games he’s played against the Patriots.
