Untill one of them wins the SB, you will see no real change. Even then, it would be considered a fluke. Most mobile QB's are runners first and throwers second, and they are the ones that will never really make it in the pros. Elway was the last mobile QB to win it all, and by the time he did it he was noway near as mobile as he was as a rook.
Realistically, only Roger, Elway and Young could be considered mobile QB's that have won it all. Many more times the number of statues or near statues have won it all.
Starr, Dawson, NAMATH, Stabler, through the late 60's into the 70's. Plunkett, in the 80's, then Favre, Warner, and the bus drivers the Ravens, Bucs used. Montana was somewhat agile, but not all that mobile, especially later on. Theisman was mobile, but he really was not the center of the offense. Simms was not very mobile, neither was Hostetler. Aikman was no Vick, either. Any way you look at it, very few scramblers have ever won it all. Untill you get a few doing it in a short time, it will never catch on. I have always thought that if you could get three really good running QB's, like Young and VIck on one team, it would be very interesting to run the option in the pros- imagine how hard it would be for the D's? The Navy runs the option in college ball and gives teams with much better talent fits due to the rarity of the offense.
But like I said, you would need 3 to do it, because they would take a real pounding.
Have a small, agile O line like Denver, a couple of backs like JJ, and some big physical receivers who like to block downfield, and you could give every DC in the pros heartburn.
