A former All Pro cornerback is on the free agent market.

The Raiders released Marcus Peters on Monday after benching him during their Sunday loss to the Chiefs. During the game, he missed a tackle and got into an argument on the sideline with Raiders interim head coach Antonio Pierce.

Will the 49ers sign Peters?

Cornerback is one of the weakest positions on the 49ers, who admittedly don’t have many weak positions. Before the bye week, Isaiah Oliver was the 49ers’ No. 3 cornerback, and they had to bench him because he was struggling so much. Now Ambry Thomas is their No. 3 cornerback, and he has played well for the past three games, but he also has had some extremely bad games in his career. He’s unreliable.

And then there’s Peters, who has intercepted 33 passes in his career. He has been one of the biggest playmakers in the NFL since the Chiefs drafted him in 2015. But he has played on four teams in his career, he’s 30, he doesn’t tackle well and he hasn’t covered well the past two seasons, either. Last season, he gave up a quarterback rating of 113.7. This year, he’s giving up a quarterback rating of 100.9.

Peters isn’t fast anymore. He has to give the receiver he’s covering a big cushion, which means he’ll concede short passes.

That’s exactly what Isaiah Oliver did, and that’s why the 49ers had to bench him. They don’t want to concede short passes. They want to take those away and force the quarterback to hold the ball so the pass rush can sack him.

Instead of signing Peters, the 49ers would be better off with the young cornerbacks they have already.
