FOXBORO, Mass. >> After the Patriots were embarrassed by the Jets on “Thursday Night Football,” New England head coach Jerod Mayo wasn’t ready to name a starting quarterback.

After a late-night post-game film session, however, Mayo affirmed his committment to Jacoby Brissett for this week’s game against the 49ers.

Mayo said Monday morning on WEEI radio that after a sleepless night of re-watching the 24-3 loss to the Jets, he still believes Brissett, not rookie Drake Maye — who replaced Brissett late in Week 3 — gives the Patriots the best chance to win at San Francisco.But Brissett needs help.

“Right now, Jacoby is still our starting quarterback,” Mayo said. “Even after the game, I watched that film the whole way back home. I got in early in the morning and still felt the same way. We have to support him across the board as a coaching staff and as players. We have to support him, keep him clean, and hopefully give him opportunities to look for the open receiver.”

Brissett has been under pressure on a league-high 46.7% of his dropbacks, per PFF. Brissett has only been the cause of that pressure 8.6% of the time, which ranks 25th-highest among 31 qualified QBs. The offensive line has been responsible for pressure 88.6% of the time, ranking 10th-highest in the league.

“I’ll be honest with you, Thursday, it was a very ugly day and ugly game. One thing we always hang our hat on is being able to control the line of scrimmage,” Mayo said. “You guys have heard me say it time to time again. Couldn’t do that.”

The position most responsible for that pressure on the quarterback is left tackle at 37.1%, which is third-highest in the league.

That shouldn’t come as much of a surprise. The Patriots have played three games and had four players align at left tackle. Chukwuma Okorafor started Week 1 and was benched for Vederian Lowe after 12 snaps before ditching the team and being played on the left-squad list the following Saturday. Lowe started Week 2 but suffered an injury late in the game and was replaced by rookie Caedan Wallace, who started Week 3. Wallace got hurt late in Week 3 and was replaced by Demontrey Jacobs, who was claimed off waivers from the Broncos in late August.

Wallace looks like he escaped a major injury, while Lowe was still not participating in practice Monday. So Wallace looks like the favorite to start this week against the 49ers with Jacobs serving as a backup.
