I'm kinda surprised nobody is commenting on our DE's covering in space. I saw Chad Thomas in coverage today. However, I don't remember if it was lined-up at an OLB position or if he dropped back in a zone blitz.
There's nothing wrong with having LB's over slot WR's. That's common. He's not playing man on the slot, he's playing zone. Nothing wrong with that. If your OLB's can't play the flats and/or hook-to-curl zones then they don't belong at Miami.
What's wrong is when you have nobody out there at all.
