This spread is funny to me. The books are obviously not thinking the public will be liking AZ too much, making them 3 point dogs at home, with AZ's vig at +110.
This seems to be a line geared towards the sharps, who I assume will be on Philly hard. The books are trying to take in some extra vig before they have to move the line to 3.5. The Eagles have the secondary to match up with great WRs, and are one of the best blitzing teams which is good when facing a team that passes as much as AZ. The squares will be fooled by the last 2 weeks into thinking AZ can actually run the ball now. Don't bet on that.
Only 2 things worry me. One is that I'm not sure how healthy Westbrook really is, and the other is the always possible McNabb meltdown, but I don't predict one of those.
I just cannot see the Cardinals in the Super Bowl. Maybe this is the year McNabb finally gets his ring. I haven't made up my mind yet, but early lean on the Eagles and the Under 48.
