Richard Sherman knows what it's like to leave the only franchise he's ever known to join the 49ers.
So, what does he think about Antonio Brown's desire to play in San Francisco?
"Good luck to him," Sherman told TMZ on Thursday night in Los Angeles.
The All-Pro receiver wants out of Pittsburgh and to come to the 49ers "really badly," according to Hall of Famer Jerry Rice.
Steelers owner Art Rooney II has said the team won't release Brown but will explore all other options, including a trade. Rooney also said he expects discussions regarding Brown's future to heat up in mid-March when the new league year begins.
