Spread or any system is one thing.. Bama got beat by an all around solid football team that got great play from a great player in JFF.
To me, it is not fair to the defense that the offense is set and ready for a couple seconds while the defense is struggling to get in position ON PLAYS WHERE THE OFFENSE SUBSTITUTES. I have no issue with the no-huddle offense as long as there are no substitutions. Once the offense substitutes, there has to be some way to let the defense get as set and ready as the offense. From what I saw, this was a frequent problem and not just because the coaches "weren't prepared".
