Is it? Need another opinion?

In 1990, 18 of the NFL's 28 teams were in the 3-4. By 1994, only five teams were using the 3-4, and the number dropped to four by 1995.
Now....
Six of the seven head-coaching hires this offseason have defensive backgrounds. Defensive coordinator Vic Fangio could move the Chicago Bears from a 4-3 to a 3-4, while coach Rex Ryan in Buffalo and defensive coordinator Wade Phillips in Denver are expected to do the same.

That would bring the number of 3-4 defenses in 2015 to 17, the most since 1990.

After spreading through the NFL and much of college football, odd defenses -- with three down linemen instead of four -- will be more visible in the Big Ten this season. Three Big Ten teams -- Wisconsin, Maryland and Indiana

Point is it's spreading due to 2 factors.

1- Better vs the spread
2- Easier to recruit for.
