For every Plan A, there needs to be a Plan B.

For right now, that’s quarterback Jacoby Brissett with the Washington Commanders.

With preseason drills starting this week in Ashburn, second-year pro Sam Howell will likely be in day to day competition with newcomer Brissett for top gun status.

Brissett, who signed a one year, $10 million contract in March, has an enormous advantage in NFL experience, and long-term success.

But Howell, in his only 2022 showing, led the Commanders to a win over the dreaded Dallas Cowboys in the final game of the season to finish 8-8-1. He is on a four-year, $4 million contract.

The win over Dallas is fresh in the minds of restless Washington fans and, perhaps, with the coach’s assessments (including new offensive coordinator Eric Bieniemy).

By most accounts, Howell has a slight edge over Brissett.

Much will be determined during the exhibitions Aug. 11 at Cleveland, Aug. 21 at home against Baltimore and Aug. 26 at home against Cincinnati.

Last year’s regulars Carson Wentz (now a free agent) and Taylor Heinicke (with Atlanta) are gone, creating a vacancy.

The preseason competition will have much to do with whether Howell, 22, or Brissett, 30, is under center for the true opener Sept. 10 against invading Arizona.

Both Brissett (North Carolina State, 2013-2015) andHowell (NorthCarolina, 2019-2021) come from the ACC but never overlapped on the college level.

A third round draft pick by New England in 2016, the 6-foot-4, 231-pound Brissett played for the Patriots (picking up a Super Bowl ring as Tom Brady’s backup), Colts, Dolphins, and Browns (2022) before coming to D.C.

For his career, the native Floridian has completed 61.1 percent of his passes for 10,350 yards with 48 touchdowns and 23 interceptions. With the Browns last season, he hit 64 percent of his tosses for 2,608 yards and 12 TDs.

Brissett’s career record as a starter is 18-30, including 4-7 a season ago in Cleveland. His passer rating with the Browns was a career high 88.9.

Howell, a fifth round pick in 2022, has a worksheet much shorter than Brissett’s, but a bit sweeter.

The6-foot-1,230-pounder’s record as a starter is 1-0 which may give him the early nod ... that is, until something goes wrong.

That’s when Plan B would go into effect.
