[QUOTE="slugboy, post: 858674, member: 282"] Since I pulled the [URL='https://www.footballoutsiders.com/stats/ncaa/sp/overallol/2021']Football Outsiders data[/URL], here are a couple of more charts If you want to skip the rest--we got better in the run stats but got worse in the pass stats. There's progress, but not on the passing side that would make an RPO offense hum. [LIST] [*][B]Opportunity Rate[/B]: The percentage of carries (when four yards are available) that gain at least four yards, i.e. the percentage of carries in which the line does its job, so to speak. [*][B]Power Success Rate[/B]: [URL='https://www.footballoutsiders.com/info/glossary#power']This is the same as on the NFL side[/URL] -- percentage of runs on third or fourth down, two yards or less to go, that achieved a first down or touchdown. [*][B]Stuff Rate[/B]: [URL='https://www.footballoutsiders.com/info/glossary#stuffed']Same as STUFFED on the NFL side[/URL] -- percentage of carries by running backs that are stopped at or before the line of scrimmage. [/LIST] These are all RANKS in this chart, so you want to be #1 (hugging the bottom). It's tough to separate a play where the running back or quarterback dodged 6 people in the backfield before making a 10-yard gain vs the line pushing for 10 yards and the RB following them the entire way--and these stats don't do that. But whether it was having great RBs or better blocking, we got better on the ground in 2021. [ATTACH type="full" alt="1641304519743.png"]11934[/ATTACH] In terms of how many yards we got, we became more effective in the run in 2021, but less effective through the air. [LIST] [*][B]Line Yards per Carry[/B]: For 2018, we are experimenting with a new definition for college line yardage based on film study and generalization. Instead of [URL='https://www.footballoutsiders.com/stats/ncaa/sp/overallol/m/info/glossary#aly']the ALY figure FO used for the NFL[/URL], this one is tighter: the line gets credit for rushing yardage between 0-3 yards (instead of 0-4) and 50% credit for yards 4-8 (instead of 5-10). Anything over 8 yards is quantified as a highlight opportunity, and credit goes to the runner. As with the pro definition, lost yardage still counts for 125%. (Garbage time is filtered out for all line yardage averages.) [*][B]Standard Downs Line Yards per Carry[/B]: The raw, unadjusted per-carry line yardage for a team on standard downs (first down, second-and-7 or fewer, third-and-4 or fewer, fourth-and-4 or fewer). [*][B]Passing Downs Line Yards per Carry[/B]: The same unadjusted averages for rushing on passing downs. [/LIST] [ATTACH type="full" alt="1641304978134.png"]11935[/ATTACH] In pass blocking, we weren't good before the previous three seasons, and we're still not good [LIST] [*][B]Sack Rate[/B]: Unadjusted sack rate for all non-garbage time pass attempts. [*][B]Standard Downs Sack Rate[/B]: Unadjusted sack rate for standard downs pass attempts. [*][B]Passing Downs Sack Rate[/B]: Unadjusted sack rate for passing downs pass attempts. [/LIST] These stats don't separate out a QB holding the ball for 10 seconds vs having a Dan Marino quick release, but Sims and Yates didn't have a comfortable pocket.
