I sometimes run 3-4 odd, especially inside my 10; and in some plays one or even both my OLBs drop into coverage.
I normally use Derrick Thomas and Dee Ford, they're both Speed Rusher archetype = not that great in coverage:
Thomas 79 ZCV, 62 CTH
Ford 73 ZCV, 55 CTH
I've been thinking, maybe I should sub in some coverage OLBs, like Kevin Pierre-Louis (92 ZCV, 72 CTH), but I'm too lazy for that.
Funny thing, in my last 2 games I got 2 picks from Thomas and Ford
