Carolina Panthers middle linebacker Luke Kuechly isn't satisfied.
Kuechly became the first rookie since San Francisco's Patrick Willis in 2007 to lead the NFL in tackles last season and was selected AP Defensive Rookie of the Year after recording 164 tackles, three fumble recoveries and two interceptions.
Kuechly downplayed those numbers, saying the focus is on getting better.
''If I can improve on my pass coverage I'd be real happy with that,'' Kuechly said.
Panthers coach Ron Rivera said Kuechly is light years ahead of most young linebackers in the league and thinks he's destined for greatness.
''He's developing into one of the best middle linebackers in the league,'' Rivera said.
Rivera has learned two things about Kuechly - he's best when he plays middle linebacker and leave him alone.
Kuechly, who twice led the nation in tackles at Boston College, moved to middle linebacker five weeks into the 2012 season after Jon Beason went down with a season-ending injury.
