Mike Mularkey says he's not seeing enough from Tennessee Titans rookie Derrick Henry.

"I will say this about Derrick: I don't think he's a fast starter," Mularkey said. "I've got to talk to him about that tempo period because we've got a bunch of guys up front that are creating things for him and he's not hitting it like I'd like to see him hit it, [like he is] later in the practice.

"I hope that's not the case in games. We need him to be full strength. As soon as we call his number, he needs to hit things better."

The Titans drafted Henry with the 45th overall pick in this spring's draft.
