which 4-3?

The 4-3 under or Tampa 2
The Seattle hybrid 4-3 with cover 3?
The Eagles (maybe Schwartz himself?) wide 9 4-3?

I assume you don't have an issue with zone coverage? Seems to me the majority of NFL coverage is zone these days, you'd know more than I do, but I'd guess 66% zone 33% man? Is that too high? Too low? I don't know.

I personally was a big fan of Dick LeBeau's zone blitzing 3-4 Pittsburgh defense.
