The three teams that have shown the most interest in wide receiver Antonio Brown to date are the Oakland Raiders, Washington Redskins and Tennessee Titans, league sources told ESPN.

Thus, the pursuit of Brown could develop into a battle between Grudens: Raiders coach Jon and Redskins coach Jay.

Other teams have had conversations with the Pittsburgh Steelers, and another could emerge. But the belief as of now is that the Raiders, Redskins and Titans are the most likely landing spots, sources said.

The Steelers' asking price started as a first-round pick and other compensation but has been reduced to a first-round pick. That doesn't mean the Steelers will get it in return for Brown, but their goals are now more realistic.

Brown has officially been on the trading block since he met with Steelers brass last month.

In an interview with ESPN earlier this week, the star wide receiver said he is not "angry" with the team but maintained his desire to be traded.

Speaking at the NFL scouting combine in Indianapolis earlier this week, Pittsburgh general manager Kevin Colbert said the team hasn't ruled out any partners in a potential trade.

"Ideally, you want to trade him to somebody that you'll never play," Colbert said. "But you can't do that. If you're good enough to get to the Super Bowl, you have to play him anyway."

Brown, who turns 31 in July, owns an NFL-record six consecutive 100-catch seasons, but he frustrated the organization when he failed to show up for a workday in Week 17 and was benched for the season finale.
