Brunell vs. Bledsoe

[That Guy]

what parameters do you want on it? If you want you can treat each team as an equation and each year givess you 32 equations... you compile that data and you can data mine it any way you want.

using all the data to find the one you want, like yearly passing yards for a 10-6 season with 1500 yards rushing and a 10th ranked defene or whatever. Or use it to factor out the differences between a run heavy and pass heavy teams stats.

In the end the stats as they are work well enough that there's no really need to go into that though. you can look at sacks and the QBs escape ability (measured from bledsoe to mcnabb) and have some idea how much of that is on the OL and how much is on the QB.

you can look at fumbles/sack and fumbles/play (or per play hit, to avoid OL factoring in) for QBs to see their ball security averages (with alex smith being one of the worst).

what exactly are you looking to prove and how in depth does it have to be? stats are a measure of production, and when people talk about who's better, they generally mean in terms of production. jim brown is good cause he was productive and he was able to generate wins. Manning is productive because he OD's on film study and produces crazy passing stats.

if manning had moss and cooley and the junk WRs we had last year, he'd put up better numbers than brunell. his stats prove that by the crazy difference in TD/INT, TDs, yards, completion % etc.

If two players are close you can argue the stats may be misleading, but in many cases they point out the obvious quite well. manning isn't the lottery winner of a good scheme, he's the driver. if he had junk WRs his stats wouldn't be as good, but they'd clearly be better than putting brunell or vick or alex smith in the same situation.
