Damn, I meant to qualify those numbers with "as a starter" distinction. Like Harry said a while back when Leinart went down, a little of Warner is a lot better than a lot of Warner.
Aha, that explains it. I wasn't disputing that Warner fumbles too much, of course!
A couple games after Warner took over as the starter, when discussion of Warner's positive and negative attributes was heating up, i put together a spreadsheet comparing various QB's TD-TO differential, on a per-game and per-attempt basis. I selected an arbitrary group of QBs who have been very good for several years for comparison.
Never got around to posting the details then and won't bother now, but the bottom line is that from 1998-2001 with the Rams, Warner's average (TD-TO)/Att was about +2.5% - on a par with Peyton Manning's career average, and better than Brady's (+2.0% as of game 7 this year), Favre's (+1.0%), Hasselbeck's (+1.2%), McNabb's (+1.5%), etc.
In 2002-2003 with the Rams, Warner's differential went to -4.5%! 2004-2006 with the Giants and Cardinals, it was within a few tenths of -1.0%. This year, after game 7, it was 0.0%... and based on the current 21:21 numbers, it still is.
Another interesting thing i looked at was Fumbles Lost per Sack. Hasslebeck led the pack over his career with 6.2%, followed by Manning at 9.2% and McNabb at 12.2%. Brady came in at 14.3% and Favre at 14.5%.
Warner (after game 7 of this year) was at 15.5% for his career, but interestingly that breaks down to 11.5% from 1998-2001, and 18.7% from 2002-2007. Breaking down Warner's "post-prime" years further, Warner had 11 fumbles vs. 41 sacks from the time he joined the Cardinals in 2005 to the 7th game of this year, or 26.8%!
At some point perhaps i'll factor in the rest of this year's stats, but i don't think doing so will make much difference in trends that are already so apparent.
