This year, ESPN has rolled out a ranking system for college quarterbacks, similar to what ESPN developed for pro QBs last year. ESPN's College Football Total QBR scores are currently available on ESPN's College Football main page, and I've summarized the scores for all SEC quarterbacks this year below. To try to get the data to line up right, I've shortened some of the players names. Rnk PLAYER PASS RUN SACK ACT RAWQBR 8 Mettenberger, LSU 20.3 1.0 -1.3 92 91.6 20 Jmes Franklin, MIZZ 12.1 5.5 -2.1 90 84.2 24 Jnny Manziel, TA&M 15.2 5.9 -1.9 127 82.1 29 Brandon Allen, ARK 9.6 2.5 -1.4 64 81.0 31 Aaron Murray, UGA 19.5 -1.3 -4.5 74 79.5 35 Bo Wallace, MISSIS 15.7 7.2 -2.7 130 77.0 38 AJ McCarron, ALABA 9.8 0.0 -1.4 64 73.8 41 Nick Marshall, AUBU 11.0 4.5 -2.4 103 71.0 42 Dak Prescott, MSST 5.4 5.9 -0.3 102 70.6 45 Connor Shaw, USCE 14.2 0.6 -1.3 127 70.1 47 Justin Worley, TENN 3.6 0.8 -0.1 68 68.4 51 Jalen Whitlow, UKEN 1.9 5.7 -1.0 77 65.9 74 Carta-Samuels, VAN 6.7 2.6 -3.3 110 55.5 88 Jeff Driskel, UNIVFLA 6.9 1.1 -3.9 79 50.0 Anybody can read ESPN's explanation of how they run their analysis on ESPN's website, but I'll briefly describe each item as I understand it. Basically, ESPN's analysis tries to control for the quality of the defense and tries to apportion credit on each play to the QB, the receiver, the offensive line, etc. So I think there's a subjective aspect to their rankings. And of course, the ratings are only through week 3 of the college football season. The overall rank is out of 132 college football QBs--1 is best, 132 is worst. Driskel is ranked 88 out of 132, and he has the worst overall ranking of the 14 QBs in the SEC. PASS score is the number of expected points added on passing attempts during a whole game. Driskel has a score of 6.9, which means his performance adds a total of 6.9 points for the Gators each game. Driskel does better on passing plays than Kentucky's QB and Miss St's QB, and about the same as Vandy's QB, but worse than all the others. RUN score is the number of expected points added through QB rushing plays during a game. Driskel has a RUN score of 1.1, meaning his running accounts for 1.1 total expected points per game. Driskel's RUN score is better than 5 other SEC QBs, but adding 1.1 points per game doesn't seem like a lot. SACK score is the number of expected points lost during the game because of QB sacks. Aaron Murray costs his team 4.5 points each game because of the sacks he takes, which is the worst in the SEC, but Driskel is second to worst in the SEC with a SACK score of -3.9. I think the ACT score is just the total number of "action plays" for the player--in other words, the number of plays where QB play is evaluated. For example, when the QB hands the ball off to a running back, the QB doesn't get any credit or blame for that play--that's my take at least. RAWQBR is the 0-to-100 final score for the QB, where 50 is average. Don't ask me why the median total QBR score across all QBs is 58.6 and not 50. I talked to Dean Oliver, who is the Director of Production Analytics at ESPN and oversees the development of both the NFL and college total QBR systems, and I asked him to explain to me why Driskel's rankings were so poor. He told me that Driskel hasn't done well on third down conversions. ESPN's rankings are all clutch-weighted, which means third downs are more important. Success on third downs is where a QB really can improve the amount of expected points the team is going to score. Based on this analysis, I think a nice place for Jeff to start is to not take so many bad sacks. Converting more on third downs would be nice too, but throwing the ball away seems like an easier thing to fix quickly.
