When Tebow headed up the 2011 Broncos, once the ball got to the 31 yard line of the opposition or inside of that, they ran the ball fifty nine percent of the time.
If you've got a QB who while inside the red zone, runs the ball in for a score 37 to 38 percent of the time, runs the ball for a first down just as often, then we're not even talking about your "average NFL" team...and to think this article was addressing the "average NFL" team...as if the "average NFL" team would buy into what this article highlighted isn't paying close attention.
That was a team with a very bad QB who threw completion less than 50% of the time relying on the one thing he could consistently do: run. The league as a whole is a passing league. Nobody has their QB run by design more than 10% of the time, even teams with good running QBs (Seahawks, Steelers, Colts) know volunteering your QB to get tackled is a risky plan. Just look at the Redskins, planning on running the QB often cost Shanahan his job, and the damage he left behind is probably going to cost Gruden his job.
The article says “past time for the NFL to consider”, anything the league should consider would be for the average NFL team. If it isn’t for the average team then it is NOT time for the league to consider. If it’s only something to be considered for teams who have QBs that can’t actually throw the ball that’s not the league, and those teams would probably be better served by getting one QB that doesn’t suck rather than squading multiple bad QBs.
