The San Francisco 49ers are considered by many to be one of the top potential landing spots for disgruntled Pittsburgh Steelers wide receiver Antonio Brown, but 49ers head coach Kyle Shanahan said that the 49ers have not even reached out to the Steelers, according to Eric Branch of The San Francisco Chronicle.

However, Shanahan did not close the door on the possibility of San Francisco pursuing a trade for Brown:

“We’re in the market for anything that makes our team better at every single position,” Shanahan said.

Obviously, Shanahan is approaching this in a diplomatic manner, not wanting to play his team's hand. That being said, the 49ers, like every other potential Brown suitor, will likely go into these trade talks with a measure of caution.

While Brown remains an incredibly productive wideout, his tendency to cause locker room issues cannot be ignored.

The reason why he is on the outs in Pittsburgh is because of a series of events that occurred in the week leading up to the Steelers' regular season finale. Brown got into a heated argument with Ben Roethlisberger that apparently ended in Brown throwing a football at the quarterback. He then refused to practice, complained of knee pain but refused to go for an MRI and went AWOL on the team before being consequently benched by head coach Mike Tomlin for Pittsburgh's Week 17 matchup against the Cincinnati Bengals.

On the season, the 30-year-old hauled in 104 receptions for 1,297 yards and a league-leading 15 touchdowns en route to his sixth straight Pro Bowl appearance.
