I think the clock runs according to whatever you have with the stopped progress and really has nothing to do with him being knocked out of bounds. Stopped progress is stopped progress regardless of how it occurs. There is the possibility of progress being stopped without the player being controlled. Say a runner has advance to the 40, is hit by a defender that takes him straight back so the first thing that hits the ground is his back side at the 42. Just one of those hilite film big hits. Are you going to spot the ball at the 40 (progress spot) or the 42 (down spot)? Throw the sideline in, say because of the hit he flies OOB at the 42. Where do you spot the ball? So why, when dealing with an airborne receiver being knocked OOB do we suddenly ignore the dead ball rules stated in 4.2.2?
Hey, and for Sundays it is apparently all going to be a moot point. Per a San Diego Union article this weekend, Mike Carey was instructing the Chargers about some new rule changes for this year, one of them being if the receiver gets knocked out prior to getting both feet down, it's incomplete. No more judgement calls on would he have landing in. Also, it seems the NFL is going to allow a defer option on the coin toss now.
