SF 49ers vs. Bills: 5 biggest disappointments from Week 13 loss

Disappointment No. 1: SF 49ers having no answers for Cole Beasley

It was no secret San Francisco was going to have a tough time defending against Josh Allen and Buffalo’s prolific passing offense.

And while No. 1 wide receiver Stefon Diggs was a major factor, few likely thought slot receiver Cole Beasley, who’s actually the Bills’ second-best target this season, would be such a massive force. Entering the game with 57 catches for 667 yards and three touchdowns, he was going to be an X-factor.

But it’s disappointing from the SF 49ers’ vantage point just how big an impact he’d play.

Beasley led all receivers in the game with a career-best 130 yards and also scored his touchdown against veteran cornerback Richard Sherman, who himself was pretty disappointing in the contest.

Granted, the Niners were down three nickel cornerbacks: K’Waun Williams, Jamar Taylor and Emmanuel Moseley. Yet one has to figure coordinator Robert Saleh could have devised a game plan to limit Beasley after he started to become a key factor early in the first quarter.

Saleh didn’t, though, and Beasley made San Francisco pay time and time again.
