Are you now arguing that a college offense should be judged by how much success All-Americans have in the NFL? Then I guess the spread doesn't work. Alex Smith was a bust!
Just out of curiosity, how old are you? (I'm not trying to be a smart ass by asking this.) Are you old enough to have seen the wishbone/I-bone triple option offenses of the '80s and early '90s? If so, I don't know how you could possibly think the modern spread bears any resemblance to or is in any way related to what we ran back then.
The spread most certainly DID NOT evolve from the triple option. See the Wikipedia page for the spread if you don't believe that.
Spread Offense
The triple option was smashmouth football in the truest sense. It was far more run oriented than any pro style offense. It was common for teams that ran it to pass the ball fewer than ten times per game. The few pass plays we called were almost always play action. In 1989 Darian Hagan was a Heisman trophy finalist. He averaged 7.7 pass attempts per game. The team ran the ball 666 times. We passed it 102 times. That's right, we ran the ball 86% of the time! Hell, we'd run the ball on 3 and 10+ and make it half the time! We lined up with a FB and TE on almost every play. In short yardage or when we just really wanted to pound the ball, we brought in a second TE. Our #1 receiver, Mike Pritchard, was actually a wingback. He often lined up in the backfield and blocked. There was NO SHOTGUN EVER!
Does that sound anything like the modern spread? Have I have convinced you that the spread and the triple option are unrelated yet?
