Teams immediately set up meetings with free agents

Free agency opened with an explosion of phone calls to set up visits for the 308 NFL available players.

Teams couldn't contact agents of free agent players until 12:01 a.m. ET Friday. Once they did, visits were set up for later in the day. The Broncos, Seahawks, 49ers and Browns were among the most aggressive teams.

Bengals guard Eric Steinbach is heading to Cleveland for a visit, with secondary trips set up with Tampa Bay and Seattle. The Seahawks talked Chargers guard Kris Dielman into making Seattle his first stop. Falcons defensive end Patrick Kerney will begin his free agency tour in Denver. If no deal is worked out there, Kerney is off to Seattle for a visit.

Patriots tight end Daniel Graham visits the Broncos on Friday and has the Seahawks on his list of visits for later in the weekend. The Vikings persuaded Rams wide receiver Kevin Curtis to visit them first, but there could be weather problems. Most people thought Curtis would go to Detroit. The Vikings are also scheduling a trip for Giants tight end Visanthe Shiancoe for Friday.

Leonard Davis of the Cardinals hasn't scheduled a trip because negotiations were heating up with at least three NFC East teams, including the Dallas Cowboys.

Ravens tackle Tony Pathos scheduled a visit to Jacksonville for Friday. Falcons fullback Justin Griffith plans to go to Tampa Bay. The 49ers are expected to get a visit from Ravens linebacker Adalius Thomas. The Redskins were expected to be working on Bills linebacker London Fletcher. Colts halfback Dominic Rhodes plans to visit the Giants. Bills cornerback Nate Clements was talking to the Browns, Titans, 49ers and several other teams.
