With Ronnie back (the only "trigger man" who had real success unless Pat White makes a miraculous upgrade) I think we keep the 'Cat if nothing for the added complexity it poses to opposing defenses. If they don't prepare, they get a heavy dose of it and we are more likely to win. They do, we shift to our bread-and-butter formations and play on. The Wildcat doesn't have to take Marshall off the field and can be more effective with a big target like him for an inexperienced QB (Brown or White) to throw to.
