They aren't apple and oranges but they are different things. Naturally, because this team is going to likely pass a heck of a lot more, more interceptions are going to be made. You have less control over a ball in flight than you do the one in your hands. It seems reasonable to think the two should be handled differently. However, if Romo is chucking picks and making mistake after mistake or really poor decisions? I honestly wouldn't be all that offended if he was temporarily benched for a quarter. Sometimes you have to play it safe and be a bus driver. We've had situations where games have been thrown away before because of Romo and his poor decisions. If they can't get it across to him any other way, perhaps a temporary and short benching would do it.
Yeah, it would cause media waves, but who cares. This team has always had the media all over it. If Romo has handled the criticism thusfar he can handle pretty much any other criticism that will come his way. I think the message should be clear and fair and applied equally, even if the punishment isn't necessarily equal. Everyone on this team should be held accountable, including Romo.
