This past season was a mixed bag for SEC fans. On the one hand, the conference lost its national championship streak. In fact, the league was (gasp) second to the Pac-12, according to at least one measure.

On the other hand, the league produced consistently thrilling games, with a series of high-scoring gems culminating in Auburn's 109-yard missed field goal return against Alabama. Unless you hate fun, it was a great year to be watching SEC football.

Part of the reason was the crop of experienced, talented quarterbacks. At the forefront were Manziel, McCarron, Mettenberger, and Murray. The quartet occupied the top four spots in the SEC rankings for passing yards per attempt and four of the top five spots (joined by South Carolina's Connor Shaw) for adjusted yards per attempt and pass efficiency rating. Now, all four are headed to the NFL.

The consensus of Draft analysts is that Johnny Manziel is the best NFL prospect in the group, with McCarron, Mettenberger, and Murray in some order in the tier behind. SB Nation has the order Mettenberger-Murray-McCarron. Manziel is expected to be off the board in the first 10 picks; the remaining three should be gone between the late first round and the middle rounds.

Now, a simple point: with the possible exception of Manziel, Aaron Murray is the best SEC quarterback Draft prospect in 2014.

I'm not making this case based on any scouting acumen, of which I have none, other than the ability to chuckle at Taylor Martinez's throwing motion. Instead, I'll cite the predictive model developed by Football Outsiders for assessing quarterback Draft prospects. Using regression analysis to determine which factors correlated with future NFL success, David Lewin created the Lewin Career Forecast. It found two factors -- games started and completion percentage -- to be the most important when guessing whether college quarterbacks would succeed.

For instance, LCF spotted Mark Sanchez's bust potential, based on the fact that he started only one season at USC. If he were an elite quarterback, then why was he sitting behind John David Booty for two years? And how risky is it to spend a high pick on a guy who made only 487 college passes? LCF predicted the rise of Russell Wilson, who'd started for four years. Wilson threw 1,489 times in college, which gave scouts a much better sample size and gave Wilson more opportunities to learn.
