Need a reminder not to sleep on Oklahoma? Here you go.

We didn’t get into the Sooners too much on Thursday during our breakdown of the returning experience on every Big 12 roster. But here’s a look at another piece of the puzzle: offensive production.

Which teams get their passers and playmakers back? Which ones are starting fresh? Below is a breakdown, in percentages, of how much passing, rushing and receiving production (in yardage) each team brings back from last season.

Returning Production The percentage of passing, rushing and receiving yards each Big 12 team brings back from the 2014 season, based on their returning players. Team Pass Rush Rec. Total Oklahoma 100 86 85 90 TCU 96 83 86 89 Texas Tech 97 97 75 88 Iowa State 99 39 52 68 Texas 93 62 30 62 Baylor 19 87 78 57 Oklahoma St. 35 29 89 55 Kansas 100 38 7 50 West Virginia 20 72 39 39 Kansas State 6 47 19 19

The Sooners look pretty good by these measures, bringing back two starting quarterbacks and at least 85 percent of both their rushing and receiving production. That is a fortunate situation for new offensive coordinator Lincoln Riley. Whether all those returning pieces fit where he wants to take this group with the Air Raid remains to be seen, but experience counts.

A few more takeaways:

Kansas also brings back 100 percent of its passing production, though that number doesn’t factor in Michael Cummings’ injury. Texas Tech brings back 97 percent of its rushing after losing only Kenny Williams. Oklahoma State has pretty much everyone back at receiver (89 percent), as do TCU and OU.

Only one program lost the majority of its production in all three areas: Kansas State. Jake Waters’ graduation means K-State lost 94 percent of its passing. Without Tyler Lockett, Curry Sexton and a few others, this team is missing 80 percent of its receiving production. That offense will be filled with new faces in 2015.

If we focus only on skill players – backs and receivers -- there are four Big 12 offenses that bring back at least 80 percent of their production: Oklahoma, TCU, Baylor and Texas Tech. Nearly all of their best playmakers are back. The same is certainly not true of Kansas (19 percent) and K-State (28).

A few groups that are replacing at least 70 percent of their production in 2015: Baylor’s quarterbacks, Oklahoma State’s running backs and Texas’ receivers. Each one will be intriguing to track this season; they can boost their team’s fortunes if inexperienced players step up.

Perhaps the most startling reset: Kansas gets only 7 percent of its receiving production back for 2015. That’s 169 yards out of 2,435. For Kansas coach David Beaty, a former receivers coach, developing new talent on the outside and inside will have to be a priority early in his tenure. But, you know, that’s true of a lot of positions for KU.

We did this study last year, too. TCU brought back 80 percent of its rushing/receiving production but still had a question mark at quarterback. Baylor, on the other hand, had 100 percent of its quarterback play back but lost about half of its rushing production. They both ended up doing OK offensively.

And while their prolific attacks will get all the national attention entering the season, there are still several other offenses in the Big 12 -- we're looking at you, OU -- who appear poised to be even more productive in 2015.
