That's a massive overstatement for a scheme that hasn't proven anything yet. Miami's defensive issues last year were more fundamental than just alignment, ranking 98th in defensive SP+. A three-safety look doesn't fix a pass rush that generated only 24 sacks all season. Their real problem was a lack of disruptive players, not the scheme itself. Plenty of teams run similar concepts without a playoff jump. Until they show they can consistently get stops on third down, this is just offseason hype.
