New York Giants coach Tom Coughlin has filled out his staff for the 2013 season.

Coughlin announced Wednesday that Lund Wells has moved from offensive assistant to assistant offensive line coach. He replaces Matt Rhule, who left to become the coach at Temple.

Replacing Wells as the team's offensive assistant is Ryan Roeder, a former quarterback at the University at Albany. He spent the last three seasons as the tight ends coach at Princeton.

Robbie Leonard also was hired as the Giants' new defensive assistant. He replaces Al Holcomb, who left to become the Carolina Panthers' linebackers coach. Leonard spent last season as a defensive assistant at North Carolina State, where he was a three-year letterwinner as a linebacker.
