Really, what you do it just mix it in with your zones, fine good man to man plays that you like and possibly add in a zone or two with it and you'll be set. One man coverage that i like is cover 1 snake, i put the blitzing LB either in a purple or a yellow zone. Also, I would not suggest trying to play man against 4 or 5 wide outs, usually someone can get open. And when i say mix it in with zone, i don't mean like 50:50, maybe like 70 zone 30 man. Or just throw it at them when there not expecting it. Hope this helps.
