Anyway, Football Outsiders has a terrific article up now where they've analyzed quarterbacks taken in the first two rounds of the Draft over the past couple decades, determined that completion percentage and games started are the stats that have the most predictive power for the success or failure of a prospect, and now speculate on Cutler, Young, and Leinart in the NFL based on those stats. Some thoughts:
1. I've always thought that completion percentage was a lousy way to evaluate a quarterback and that yards per attempt was the only important stat (with touchdowns and interceptions having some value, but only secondarily so). That may still be true in terms of a quarterback's value to their team, but in terms of evaluating a quarterback's talent going forward, it appears that completion percentage is quite relevant. This makes sense, since accuracy is the #1 physical tool that a quarterback needs and completion percentage is the best way to determine whether that QB hits their spots on a regular basis.
2. The implications for D.J. Shockley are not good. Shockley only started for one year at Georgia and the fact that he was never able to beat out David Greene, a decent but hardly overwhelming starter, ought to be a major strike against him. If he can't beat out a likely career NFL back-up (assuming that Mark Richt didn't keep him on the bench for factors other than ability), then how is he expected to be starting caliber in the NFL, or even back-up caliber? And the 55.8 completion percentage is nothing outstanding, especially since it is lower than any of David Greene's season completion percentages.
3. Excellent point on Vince Young: he never had to throw the ball that hard. That would explain why he never looked like his arm was that strong, and it's also possible given how open his receivers typically were.
4. It's good to hear someone else make this point:
When it comes to adjusting your system to your players, the NFL is nowhere near as flexible as college football. This is because in the NFL players are much more expendable. A key example of this would be a man to whom many misguided people compare Young, Michael Vick. Vick has two things that he is absolutely outstanding at, running and throwing the ball far. His major weaknesses are reading the field and accuracy. Yet for some reason he has been made to play in an offense geared to short accurate passing and quick reads, so go figure.
The problem with the first part of the argument is that Mike Vick is not really expendable. The Falcons are committing a huge chunk of their salary cap to him and his back-up has a completely different skill-set than he does. As a result, the team probably has him in a system that de-emphasizes running and long passing because they don't want him taking hits that will knock him out for an extended period of time. This is why I think the Falcons need to trade Matt Schaub for a high draft pick, axe Greg Knapp, find a Vick-like back-up (Brad Smith, anyone?), and install an offense tailored to Vick's talents.
5. The biggest problem with FO's theory is that it attempts to screen out system quarterbacks like Dorsey, Kingsbury, and Wuerrfel by limiting itself to quarterbacks taken in the first two rounds, but it does not take into account the effects of systems and surrounding talent as pertaining to QBs taken in the first two rounds. For instance, this argument regarding Matt Leinart is problematic:
The most statistically similar recent college quarterbacks are Ben Roethlisberger and Byron Leftwich, both of whom played in the MAC. Leinart had better talent around him, of course, but he also had to face much more difficult competition. Dip a little further into the past, and we find that Leinart?s college statistics are remarkably similar to those of another Pac-10 quarterback: John Elway.
Leinart did not merely have better talent around him than Elway, Leftwich, and Roethlisberger, he had better talent than any of the teams on USC's schedule. As a result of Pete Carroll's skills as a recruiter, USC's location in the middle of a talent-rich region, and the ineptitude of the rest of the Pac Ten at recruiting, USC has more talent than any other college program and certainly more talent than their opponents, who have players that, with very few exceptions, USC declined to offer. (Notre Dame will ultimately challenge USC on a talent basis, but they're going to suffer the after-effects of Ty Willingham's crappy recruiting in 2007 and 2008.) Leinart had the benefit of virtually flawless protection, the best running threat in the country, and a bevy of great receivers. Thus, his stats really aren't comparable to Elway's, since Elway competed with less talent that Stanford's opponents, or Leftwich and Roethlisberger, who competed with equivalent or slightly greater talent than their MAC opponents.
