49ers cornerback Richard Sherman doesn't want to hear about opponents' records. San Francisco sits at 3-0 after a bye week; beating the Buccaneers, Bengals and Steelers, who all combine for a 3-9 record. His teammate, rookie defensive end Nick Bosa, is sick of all the critics too.

Heading into “Monday Night Football,” against the Cleveland Browns, Bosa says his 49ers have a point to prove. Via Cam Inman of the Mercury News.

“Obviously everyone will be watching on ‘Monday Night Football,’ and everyone is going to have an impression of us,” Bosa said. “We want it to be 4-0, not as a fake, undefeated team like people are saying now.”

The 49ers' 3-0 record may come from beating lower-level opponents, but that's not in their control.

They beat the Buccaneers 31-17 in Tampa Bay; the Bengals 41-17 in Cincinnati; and the Steelers 24-20 in San Francisco. Though none are playoff favorites, they did their job outscoring them 96-57. If they hadn't turned the ball over a staggering five times against Pittsburgh, the Week 3 scoreboard would be very different.

Bosa — for what it's worth — is playing up to his No. 2 overall pick status. The former Ohio State Buckeye has just one sack, but he's creating constant pressure. Per Pro Football Reference, he's recorded nine pressures, five hurries and three knockdowns.

The 49ers offense may be hit-or-miss — as Jimmy Garoppolo shakes off the rust — but their defense has been outstanding. The revamped unit is sixth in the NFL in passing yards per game (208.3) and fifth in rushing yards (75). If the defense can contain the Browns ascending offense, but shaky, offense, the critics may slowly vanish.
