having a good dual threat move the chains and eat clock also helps keep our crap defense off the field. It's a lot easier to "bend not break" when the offense has the ball +50% of the time.
If you want a great example of how to unsuccessfully implement a pro-style passing offense with subpar talent, look at KU. If you've got subpar talent (KSU), you need to run the ball, slow down the game, eat clock and not turn it over. Basically, KSU 2012-13. Or, in other words, the exact opposite of KSU 2013-14.
