Manning 2004 vs. Brady 2007
I am pretty sure many people consider Brady's 2007 campaign the best of any QB ever. I was in that category until I went back and looked a the stats in a debate I am having.
Brady 4806 yards 50 TD's
Manning 4557 yards 49 TD's
Brady broke Manning's single season TD record and threw for more yards but if you look at the efficiency numbers.
Brady 68.9 completion % 8.3 Y/A 8.7 TD%
Manning 67.6 completion % 9.2 Y/A 9.9 TD%
let me reiterate that one in every 10 passes went for a TD and almost every pass average a first down.... that's insane.
Last but not least Brady threw EIGHTY ONE more passes. So I guess it all boils down to whether you prefer efficiency or volume stats.
