Why is David Garrard up for Fed Air player of the week 5?

A quick scan through the QB numbers shows that David Garrard had one the best games in week 5.  Let's take a quick run through the numbers first.

Att 20, Comp 16, Yards 178, 3 TDs, 1 INT, QB rating 122.5.

The PFF guys gave him a rating of 5 (max that week was 6).  He had only one dropped pass, sacked once and hurried only 5 times.  His teams pass block was OK (PFF rating 1.7).  So he had good numbers at first glance, was not really pressured a lot and had OK pass blocking from his own team. 

Now let's look at the opposing defense.  Two words : BUFFALO BILLS!!!!  They have been dismal this year and they actually had a decent pass defense game in this one.  The PFF guys rank them 2nd last in pass rush, 5th last in pass coverage.  They are the worst in the NFL for opposing QB rating.  They had been lit up the previous 3 weeks by Rodgers, Brady and Sanchez.

You would expect David Garrard to have a good game against the Bills.  In fact he should have had a better game.  I'm sorry but I can't rate his performance highly against such a bad defensive team.
