"There's probably not a better duo in the league," Ravens outside linebacker Jarret Johnson said. "Hernandez, they use him everywhere. They use him as a running back. He runs a lot of vertical routes, runs a lot of underneath routes. And then Gronkowski, he's just a big, physical body who can run. You think he's 6-6, 265 [pounds] or whatever he is, but you watch him on film and he's running away from people. So it's a huge challenge for us. But you've just got to match up and play."
