Pat Shurmur of the Giants and Freddie Kitchens of the Cleveland Browns were the first coaches fired as the N.F.L. entered Black Monday, the date when the leaders of disappointing teams are traditionally sent packing.

Shurmur’s firing was announced on Monday by the team. He took over the Giants for the 2018 season and led them to a 5-11 record, which was actually a two-game improvement. This season, he handled the difficult task of benching the team’s veteran quarterback, Eli Manning, for Daniel Jones. The move seemed to pay off, as the Giants won their first two games under Jones to improve to 2-2 and get fans talking about a successful season and a bright future.

But the team then reeled off nine consecutive losses and wound up 4-12.

“Pat has been a successful and highly respected N.F.L. coach for 21 years and he is not solely responsible for our record,” team president John Mara said Monday. “But we came to the conclusion it is best to have a fresh start with the coaching staff.”
