Well, that is how real teams play winning football. You have to look no further back than the Superbowl. The Saints controlled the clock and limited Peyton and the Colts offense to 8 possetions the whole game. The Patriots played ball control the first half of last decade [feels starange to say that.] The game plan for the Giants against the Bills was ball control. I could go on, but ball control all game long is a legit stratagy. It's how I play.
A friend of mine is a Raiders fan. I was pointing out to him in 2002 and prior with Rich Gannon, the Raiders wouldn't snap the ball until the play clock was under 7 seconds, often they snaped at 1 or 2 seconds every down. The Colts were playing the Chargers two years ago in the playoffs and the TV announcers were commenting that the Manning wouldn't call his real play/snap the ball until the playclock was inside 10 seconds. The Chargers knew that and wouldn't show their real D until about 12 or less seconds. Manning countered this in the 2ed half by snaping with 15 or so left. Fun little chess match to watch play out, and to play out yourself online. But, that is asking for too much patience for most people online.
P.S. aparently running the football si cheese now? What? Oh no, blockers avctually have assignments they follow... EXPLOIT!!! The fact that you admit you can shut down their run game [just liek i can] shows it isn't an exploit. you don't need to come out in trick plays on defense to stop the run either. Just read/close lanes and play your gap assignments.
