The thing is now there are so many rules favoring offenses. cant hit high-or cant hit at all if you wanna go that far-has pretty much opened up the entire field, especially over the middle, for offenses. That lack of an intimidation factor for slot guys has given the qb's so much more leeway in types of throws that have to be made. Than you throw in the multiplicity and the technicality of the offenses today and the defenses have had to follow suit by scheming things up as well. What has developed is something that I believe is a major problem with our own defense, and that is that it's become too much of a thinking game. Then, the offenses combatted that with up-tempo. They know where their going, and theyve taken away from the defense to do any processing pre-snap, and the way offenses are ran, 1 step for a receiver is all he needs. Now, for every type of offense that has come and gone over the history of football, there has always been a style of defense that has evolved to combat it. At this, I just dont know that there will ever be anything to handle the up-tempo spreads. What we're seeing in the NFL is basically defenses resorting to a full blown guessing game. How many times do you see an NFL D line up in a 3-4, put all 4 backers AND a safety right at the line of scrimmage. 8 guys right at the line. It becomes a guessing game for o-lineman and Qb's. "Who's comin, who ain? Where can I get the hot route? Can this guy be picked up if he vacates his zone?" And so on. If you guess right, it's a 1st down. If you guess wrong, the defense wins the play.
Now, I'm not saying that the sub-300 yard defensive performance are completely obsolete, but but theyre not nearly performed as consistent as they used to be. Yards get gained. At lot of defenses are now predicated on kind of a "bend dont break" philosophy. Give some ground and hold tight in a red zone for a field goal. Or force the offense to be patient and wait for a penalty or mistake to set them back or wait for a turnover. And so on and so on.
Obviously, a large talent gap from a defense to particular offense will erase all gimmicks, but if the two are equal in talent and speed and experience, the offenses now a days have a huge advantage in scheme and rules.
