Wide receiver Derrick Williams, a third-round pick out of Penn State, was signed to a three-year deal this morning.
 That leaves just TE Brandon Pettigrew, a first-round pick out of Oklahoma State, as the only unsigned rookie. Players report today until 6 p.m.
“We’re pretty optimistic, things are moving pretty quickly now,’’ coach Jim Schwartz said this morning about Pettigrew.
  He expects everyone to report today.
 The first on-field session is set for Saturday afternoon after the players go through a battery of conditioning tests.
