Is this Marcus Maye final year ?

Good to know!

They are very certainly planning on letting him go when the season ends and looked into trading him before the season started. A very bad whiff of a signing in trying to replace Marcus Williams rather than just keeping him for $1M more.
I don't believe it was a $1m difference:

Marcus Maye signed a 3 year, $22,500,000 contract with the New Orleans Saints, including a $6,000,000 signing bonus, $14,500,000 guaranteed, and an average annual salary of $7,500,000. In 2023, Maye will earn a base salary of $1,080,000 and a restructure bonus of $6,070,000, while carrying a cap hit of $3,641,060 and a dead cap value of $18,020,000.

Marcus Williams signed a 5 year, $70,000,000 contract with the Baltimore Ravens, including a $14,965,000 signing bonus, $37,000,000 guaranteed, and an average annual salary of $14,000,000. In 2023, Williams will earn a base salary of $1,080,000 and a signing bonus of $14,920,000, while carrying a cap hit of $7,262,380 and a dead cap value of $33,998,900.
