Casserly steps down as Texans' GM

HOUSTON, May 10 (UPI) -- Charley Casserly resigned Wednesday as general manager of the NFL's Houston Texans.

He had been the only GM in the six-year existence of the expansion franchise.

Casserly's resignation comes after months of speculation about his future.

Houston has made a number of huge personnel decisions this off-season, including the firing of Dom Capers as coach in January, the surprise No. 1 pick of North Carolina State defensive end Mario Williams in the NFL Draft on April 29, and the addition of former Green Bay coach Mike Sherman to its coaching staff.

The 6-foot-7 inch, 296-pound Williams was signed the night before the draft, a move that has been widely criticized. The Texans -- who went 2-14 last season -- passed up the chance to draft Heisman Trophy-winning USC running back Reggie Bush.

The New Orleans Saints took Bush with the No. 2 overall pick.
