The offense gets run mostly from the sidelines. You score points and win the game by completing passes.
The offense gets run mostly from the sidelines.So the sideline leads the huddle, takes the snap, hands the ball off, runs with the ball, and passes the ball?
I think you're confusing the calling of plays with running the offense.
You score points and win the game by completing passes.So rushing TD's don't count? Protecting the ball doesn't count? Fourth quarter winning drives don't count?
Tebow had 17 passing TD's and 12 rushing TD's, vs 9 interceptions. He also had a winning record.
It seems to me that his accomplishments are much more convincing than your opinion.
Well, that's one way. Getting first downs by foot or by arm both keep drives going, and get in the end zone. A 5 yard completion is not inherently superior to a 5 yard run. Throwing for 300 yards and only getting 1 TD out of it isn't exactly superior either.
As an extreme example of offensive scoring efficiency compared to yardage was the Patriots 8th ranked offense which scored more than 75 points more than the top ranked offense. The goal isn't actually to make more completions, or to accumulate more yards...but rather to score more points.
