Tim Tebow remains unsigned and members of his camp are privately admitting that his career in the NFL may be over.

Tebow led the Denver Broncos to a playoff win during the 2011 NFL season, but was traded to the New York Jets when the team acquired Peyton Manning.

Tebow was cut by the Jets in April and no team appears willing to gamble on his questionable abilities at quarterback combined with the media circus that follows his every move as one of the most polarizing players in recent memory. But Tebow's abilities as a leader and a quality teammate are unquestioned.

Tebow has struggled badly with the mental side of the game, according to one source. Tebow scored below average on his Wonderlic test and is more of a kinesthetic learner.

Tebow has been offered a backup role in the Canadian Football League, though he could presumably start in the Arena Football League.

"There's no going halfway with Tebow anymore," said Tony Dungy. "You either gotta sell out and give him the keys to your team or stay away. Because, unfortunately, there's too much attention for him to be a regular, developing backup like everyone else."

The Denver Broncos have signed Quentin Jammer.

Jammer joins Dominique Rodgers-Cromartie as a free agent addition to the Broncos' secondary this offseason.

Jammer started 161 games for the San Diego Chargers.

JaMarcus Russell has lost 50 pounds and is now down to 265, his exact weight when he was the first overall pick of the 2007 NFL Draft.

Russell is receiving "significant" interest from more than one team, according to a source.

Russell would like to sign with a team where he can learn behind a respected leader at quarterback.

Russell also is "more than open" to signing with a team in the CFL.

Nate Montana is a longshot to make the roster of the San Francisco 49ers, but he participated in their one-day rookie minicamp on Friday.

Montana also attended the 49ers' rookie minicamp on a tryout basis in early May.

Montana is former backup at Pasadena City College, Notre Dama and the University of Montana.

The Atlanta Falcons will have $4.5 million in cap space cleared this week due to how they designated the release of Tyson Clabo for June 1.

The Falcons are discussing a deal with Richard Seymour, which will use that cap space.

Joe Theismann is interested in tutoring LeBron James how to play quarterback.

"I think so," said James when asked on Friday about playing the position given his ability to make such excellent long-distance passes on the basketball court. "I have the ability. I can see and read plays. I study a lot, so I know defenses and things of that nature. So I would have been pretty good if I had decided to go for it." 

"I would love to work him out and also serve as his agent," Theismann said. "I'll go wherever he wants this summer. He could play another four years in the NBA before seriously trying the NFL. ... There are not a lot of 38- or 39-year-old basketball players, but there are 38- and 39-year-old quarterbacks, so there's always time for him." 

Ramses Barden has re-signed with the New York Giants, adding depth at wide receiver.

Barden was selected by the Giants in the third round in 2009.

"I'm happy to be back," Barden said in a statement from the team. "This is where I wanted to be and now I'm here. I was out there listening to the calls, getting back into the rhythm of the cadence, enjoying the camaraderie and absorbing everything. I remember everything, I've had four years to soak it all up. I'm happy to be back on the field. I feel great. I expect the best."

Victor Cruz and the Giants continue their impasse.

Ron Jaworski is interested in signing Tim Tebow on his Philadelphia Soul team in the Arena Football League.

Jaworski first reached out to Tebow the day after he was released by the New York Jets in April and has yet to hear back.

“I love the guy,” Jaworski said. “I want him here just for his leadership.”

Tebow has yet to find a team to remain in the NFL and the team that owns his Canadian Football League rights is only offering a backup position.

“I know Tim’s in a funk right now,” Jaworski said. “But I think he’s got to have a career path. What’s he going to do to get back?”

With Michael Crabtree out for at least a sizable portion of the 2013 season due to a torn Achilles, the San Francisco 49ers could reunite with Randy Moss.

The 49ers had ruled out signing Moss earlier in the offseason.

A source close to Moss indicates he is enjoying spending time with family, but there is little doubt that he would be willing to entertain an offer from the 49ers.

Charles Woodson has signed with the Oakland Raiders on a one-year contract.

Woodson's deal is worth a maximum of $4.3 million and includes a $700,000 signing bonus.

Woodson played with the Raiders from 1998 until 2005 when he signed with the Green Bay Packers.

Woodson had met with the San Francisco 49ers and Denver Broncos, but ultimately decided to join the rebuilding Raiders.
