You are right

He invented the now popular 4–3 defense, and the "flex defense" system made famous by the "Doomsday Defense" squads he created during his 29 year tenure with the Dallas Cowboys.

But it wasn’t Owen who taught the scheme to his teammates. It was his talented young defensive back Tom Landry.

What made the Umbrella special, however, was Owen’s plan (as taught by Landry) to flex his defensive ends into standup linebackers at the snap and drop them into the short passing lanes.

The Eagle and the Umbrella were the earliest versions of today’s 4-3 fronts, but they resemble today’s 4-3 fronts in name only. Not surprisingly, it was Landry who developed some of the first innovations in the process, many of which still shape 4-3 fronts five decades later
