Maybe 8 or 9 different receivers (of various title). And no actually that’s the indication timing and rhythm is what the game is all about. The structure of NFL offense now is read and know how your team is going to react. From snap to pass is an average of 2.4 seconds, QBs are throwing to spots they know their player will be based on pre-snap read, and the only reason they know that is repetition. And no teams don’t run 55% of the time inside the 30, in the modern NFL 3rd and inches is a passing down.
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.
