Whatever goals Detroit Lions defensive end Ziggy Ansah has for his first NFL season this fall — 10 sacks? Defensive rookie of the year? — he’s not saying.

“I’m not trying to put (out any) numbers,” Ansah said this week, at a Lions youth football camp at Ford Field. “If I tell you I’m going to get 10 (sacks) and I get nine, what are you going to say?”

Nine sacks would be a good a rookie season by any measure, and something the Lions could sorely use as they try to replace starters Kyle Vanden Bosch and Cliff Avril, their sack leader the last two years.

In fact, just 31 players have had double-digit sacks as rookies in the 31 years since the NFL started tracking the stat, according to the database at pro-football-reference.com.

No rookie reached the 10-sack mark last year, but Aldon Smith (14) and Von Miller (11.5) both topped it in 2011, and Lions defensive tackle Ndamukong Suh had 10 in his rookie season of 2010.

Lions defensive coordinator Gunther Cunningham said last week that Ansah’s skill was evident in the month and a half they have spent together and that Ansah will benefit from playing a single position (right end) in the NFL after moving around between outside linebacker, defensive end and even tackle during his three-year career at BYU.

“They asked him to do more things than any college player I’ve ever seen in that position,” Cunningham said. “He played every position up front, and he is very aware of football. I don’t know how he learned all those things that quick, although I do know — there is a defensive line coach (Steve Kaufusi) that played in the NFL at BYU who coached him, and I think he was a little frustrated by moving Ziggy.
