General manager Martin Mayhew doesn't typically give away the team's scouting reports on draft prospects, but on Friday he couldn't hide his enthusiasm — especially for the quality of pass rushers who might be available throughout the draft. "There are a lot of defensive tackles in the draft, a ton of them, and there are a lot of defensive ends in the draft and free agency," he said. "I think we'll have an opportunity to add somebody to our defensive line through either of these processes. There's a ton of talent in pass-rushers, guys with developmental qualities. There're a lot of good defensivelinemen out there." One player that has intrigued the Lions, though perhaps not with the No. 5 pick, is BYU defensive end Ezekiel Ansah. "I just think he has tremendous upside," Mayhew said. "What this guy will be able to do in three or four years … you get a guy like that and the sky's the limit. He's exciting." The Lions were able to get a head start on evaluating Ansah, coaching him at the Senior Bowl. "The great thing about the Senior Bowl is really getting to see these guys in that environment, getting to see them do what they're going to do when they get to our building," he said. "At the Combine, a guy comes in, kind of knows what you're going to ask him, a lot of these guys have been prepped and you got 15 minutes.
