ok, I have no shame. What is 12 and 22 personnel?
I had the same question. Here are some pages I found with google. (It was not easy to google, I first came up with games played on Dec. 22nd and others were games with a score of 22-12. I then put in "12 and 22 football personnel").

Try my google search and you can find enough articles to read, including how it's used in the NFL, etc.
I'm a firm believer in anything that gets the running game going. I'm not an X and O expert, but I've been watching the game long enough to believe in establishing a solid running game to make your passing game more effective. It also helps the defense if you can keep the ball on the ground longer. All of this should be obvious. This is another reason why I'm not sure I agree with people that want to get a pass-happy head coach.
I looked to see if I could find a statistical breakdown of Mike Leach's offense and pass/run ratio. I found this analysis, which shows the number of touches and yardage for the "F" position, or running back. It shows that Leach does not get that much production out of the running back, either from running plays or passes caught. The article does state that WSU has historically been bad at running the ball. Well, that was not true about 25 years ago, when Dennis Erickson was there, and also ran a one back offense. His last year at WSU, Erickson had
Two 1000 yard runners: Rich Swinton and Steve Broussard. While most thought of Erickson as a pass-oriented coach, these stats from his last WSU team, which caught a lot of national attention because of its' big upset of then No. 1 UCLA, show that he ran the ball almost twice as many times as he passed: 50 rushing attempts per game to 28 passing attempts per game:

(Please tell me if I'm reading these stats wrong).
When looking back on the 1984 Orange Bowl, where we upset Nebraska, Bernie Kosar said they started to catch up on us when we got out of our pass/run balance. When Butch came back to UM, he wanted a very balanced offense; he said he had his biggest problems as an NFL DC when they faced balanced offenses.
If we run a lot of two TE sets, and get the running game going, we can give FSU a lot of problems. If we don't, it will be a long night for us. I don't mind keeping two TEs in much of the time, especially since both can be receiving threats.
