Personally, I still prefer an attacking, upfield defensive scheme regardless if it is based out of an odd or even front. The above article is interesting in that it highlights the advantage of safety coverages. I would assume this is mainly referring to split safety looks. However, typically in an even front a safety is used to balance out the numbers, particularly in the running game. All gaps are accounted for.
In the grand scheme of things I guess it ultimately boils down to whether or not Miami is able to consistently recruit an anchoring two gap defensive tackle or an athletic safety capable of playing down in the box while being equally effective in coverage. Based on the type of athletes we recruit in sFl, I think the odds are more favorable that we could find an Al Blades type of safety than a Vince Wilfork type of DT.
Let the upfront troops attack and reestablish the line of scrimmage while playing a lot of single high cover three and man 1. Just one mans opinion.
