1.) You sure about Hawks offense being more prostyle? Pretty sure he threw the ball damn near 60% of the time, took 80+% of the snaps from the shot-gun, and rarely if ever used a two back or two tight-end set. But hey keep digging.
2.) You are correct on the BCS point this year, however this has nothing to do with the point i was addressing and you still fail to understand that the current spread is nothing like the option we ran.
3.) The run and shoot was gimmicky as well for the same reason, we are in an inefficient point right now where defenses were built to handle one type of offense, and need to adjust to defending the spread.
4.) The Pro-style offense is not easier to defend if it was the NFL would run the spread. It is far, far harder to execute. You need to be much more disciplined, you need your quarterback to be bright and able to audible and read defenses a true coach on the field. You can't just rely on him turning to the sidelines to get a new play like most college teams do today. As matter of illustration look at Stanford, they certainly dont have better athletes than 18 out of 20 of the teams below them. But they run a prostyle offense, they execute it well and they are a top 5 team.
