JLD's scheme worked because it went against the conventional grain....
Just curious on what everybody opinion on him is. Where is he at now? I'm assuming retired. I liked his defense. They were attacking at all times. And I want to use my analogy on Mullen. I trade futures for a living and we go by a saying "cut your losers quick and let your winners run."
Until the late 1990's, everybody's defense was "read and react"- linemen and linebackers had an area to protect, then went to the ball only when you saw where the play was going. If you tried to slant the coaches would yell at you.
Joe Lee Dunn's philosophy was completely different- he'd send anybody anywhere. It didn't matter how you got past the offensive linemen, you just got into the backfield. When JLD's defense at New Mexico played Jim MacMahon's BYU team I 1980, they completely shut down their offense....and JLD's defense was so depleted he had one of his managers playing safety.
However, in the late 1990's- early 2000's, everybody started using Attack Defenses. Offenses could prepare for JLD's defense better. Also, when the SEC changed JUCO transfer rules (in a reaction to MSU's success), we stopped getting top players. Finally, JLD became predictable- you see a safety cheating up at the line, you KNEW he'd be blitzing...JLD never figured out that occasionally you should fake a blitz or two every once in a while.
I don't think JLD's defense would work today because most offenses are a variation of the Read-Option, where defenses have to keep their lanes.
