For some reasons, qb with high AWR will cause more run plays. After I boosted Teddy Bridgwater +10 AWR, Dominique Brown and Senorise Perry had 1,000+ rushing yards while Teddy had over 500 rushing yards.
However, you will see 5,000+ if you boost qbs such as Washington State, Texas Tech, WKU, SMU, or etc. Of course, you may want to adjust SEC coaches offense philosophy by set toward pass that will make them to throw the balls often.
