Sports-reference.com has data for QB's that includes "adjusted yards/attemp". It's a pretty decent metric imo considering how simple it is and it hammers INTs which I believe is necessary. Football outsiders, Nate Silver's team at ESPN, others, are doing more complicated stuff and it may well be better I don't know. Anyway, I think the adjusted yards sheds light...however the performance of the rest of the team (drops etc poor Zac Taylor) and the sacks, fumbles, and rushing yards of the QB are all ignored. Obviously Eric Crouch would be underrated as a QB using this metric (Martinez maybe not considering he set fumble records while racking up rushing yards).
Adjusted Passing Yards Per Attempt; the formula is (Yds + 20 * TD - 45 * Int) / Att
Stastically, Gdowski is WAY AHEAD of all other NU quarterbacks (unless you want to count things like national titles and wins and stuff like that
)
Tommy A is somewhere near the bottom relative to recent QB's (left out Lord, Daily, few others cuz I didn't care).
7.6 Armstrong, thru 3 years (53td/36int..not good) (rushing 4.2 ypa incl sacks, 15 rush TDs)
11.7 Gdowski (20TD, 2 Int) (8.0 yards per rush incl sacks, 17 TDs rushing)
8.9 Ganz (44/18) (some Cally garbage time padding assist? Nice numbers.)
7.6 Frost (18td/7int) (5.1 rush ave incl sacks, 28 rush TDs)
7.5 Frazier
(43/11) (5.7 rush ave 36 rush TDs)
7.4 Martinez (56/29) (5.1 ypa rushing, 31 rush TDs)
7.1 Zac Taylor (45/20) (maybe some garbage time padding)
6.5 Crouch (29/25..not good)
(5.3 yards per rush, 59 rushing TD's)
