Firehawk,
This is my honest opinion... football fan to football fan.
I really think you're setting yourself up for frustration and dissapointment.
For example, Cowboys fans can't even decide whether it was Aaron Glenn or Roy Williams who should be blamed for the 2 TD's Moss scored in Game 1 of the Skins/Boys games in 2005.
So, there's no way that you'll get many people to agree with your assessment of so many stats that based on your opinions of the play.
Commanders fans themselves dismiss STATS LLC, KC Joyner, and FootballOutsiders.com stats based purely on the idea that their stats gathering is "subjective" and inaccurate. See the KC Joyner: Newman Overated thread at es.com in the Around the NFL forum.
I admire your intentions though. I tried to do something similar to this, though mine was much less extensive, last season for a comparison of Roy Williams and Sean Taylor. I was hoping to find a Commanders fan that was familiar enough with the game of football as well as not being blatantly biased to track how many TD's Taylor allowed. Well, after the first 4 or 5 games, it fell to the way side and we lost track of the stats.
Anyway, in order to REALLY prove something with all this time you're going to spend, you'd better be ready to post video footage to support your breakdown of the plays. Because, someone like me (for example) that keeps each Cowboys game readily available for clip editting will be ready to pounce on anything we disagree with... and will be ready to support our argument with video footage.
By the way, it will take WAY WAY WAY longer than just 1 hour to breakdown each game if you're planning on doing multiple players. If you stuck to defensive players only it would cut your time consumption in half... trying to do QB's, RB, DB's, TE's, etc. etc. will be EXTREMELY time consuming because you'll have to be reviewing each player through each play and noting every stat you plan to track.
This is what guys like FootballOutsiders.com, KC Joyner, and STATS LLC do and even then fans dismiss them.. despite the fact that lots of their information is, in many cases, about as accurate as you could expect it to be from amateur (non-coach) examiners.
