First, let's take a look at the metrics for Brees for the 2005 season (excluding his Week 17 against the Broncos when he was knocked out with an injury)
Brees
Depth Attempts Completions Yards TD INT Pen Yds/Att
Short 304 223 1742 5 8 15 5.8
Medium 98 58 916 8 3 25 9.6
Deep 65 30 795 11 3 78 13.4
Total 467 311 3453 24 14 118 7.6
These are certainly very solid metrics. It has been said that Brees has trouble throwing deep passes, but he completed 46 percent of his deep passes in 2005. This percentage wasn't an anomaly, as Brees also completed 42 percent of his deep passes in 2004. To put that percentage in perspective, Brees finished the 2004 season with the fifth highest deep-pass completion percentage in the league, and I expect him to finish at least that high in 2005. Now let's compare these numbers against the Dolphins' tandem:
Frerotte/Rosenfels
Depth Attempts Completions Yards TD INT Pen Yds/Att
Short 329 222 1769 6 3 8 5.4
Medium 99 45 816 7 5 3 8.3
Deep 93 24 871 9 5 47 9.9
Total 521 291 3456 22 13 58 6.7
The first thing to notice about this comparison is the similarity in the short and medium pass numbers. The attempt and completion totals are nearly identical in some cases, and the other numbers are also extremely close.
