NFL Analysis: USC Quarterbacks vs. Quarterbacks from SoCal who didn't go to USC

After last Monday night's "performance" by two USC quarterbacks (Mark Sanchez 10-21 for 74 yards; Matt Cassel 10-22 for 68 yards) that make Tavaris Jackson look like Dan Marino, DBSF thought it appropriate to compare the NFL's USC quarterbacks to other QBs from Southern California, who didn't go to USC.

Career numbers for current USC QBs in the NFL:
Matt Cassel 79.3 QBRTG, 58% Completion % (Take out the New England year and this guy's Akili Smith).
Mark Sanchez 62.7 QBRTG, 54% Completion % (Most overrated player in the NFL. He threw 12 TDs and 20 pics last year, but he had Darrelle Revis on his team so that made people think he wasn't a left-handed Brady Quinn.)
Matt Leinart 70.8 QBRTG, 57% Completion % (You know you're bad when you couldn't do anything with Larry Fitzgerald and Anquan Boldin at wide receiver.)
Carson Palmer 88.0 QBRTG, 63% Completion % (Grant it, when he's healthy he's good . . .)

Career numbers for SoCal kids who didn't go to USC:
Tom Brady 93.6 QBRTG, 63% Completion % (Rumor has it that Brady's also won a post-season game or two.)
Aaron Rogers 96.6 QBRTG, 63% Completion % (Remember when he fell in the 1st round like Brady Quinn did? Well, that's the only similarity the two share.)
Warren Moon 81.0 QBRTG, 58% Completion % (If he spent those CFL years in the NFL, white people would have to invent a new passing metric so the PeytonToms of the League could own a record.)

So, there you have it: USC=we play better when we have NFL talent around us but not against us (and DBSF didn't even bring up John David Booty or Todd Marinovich).
