A little off-topic, but....
There have been a ton of QBs who gain meaningful yards, but didn't run the option. This has stuck in my craw in pondering it for Whoa Nellie.
QBs who are so elusive that a good chunk of the playbook becomes 'run around and make a play' - and I'd go so far to say HCs and/or OCs become a little lazy when they have such a luxury. They call pass plays they know the QB isn't likely to progress through, because they know he'll escape and scramble for 7 yards.
Vick was like that, and Vince Young. But so, too, were Michael Bishop, Shawn Moore, Major Harris, Brad Banks, Doug Flutie, Don McPherson, Kordell Stewart, Rick Mirer, Kevin McDougal, and Charlie Ward. Perfect read-option guys before the read-option (80s and 90s guys).
It's tricky to call a pass, then have it be a run, and in a good way. Hard to mimic in game form, anyway.
