The Cowboys signed Mayowa in 2016 when he was a restricted free agent of the Raiders. Dallas inked him to a three-year offer sheet with a $3.3MM signing bonus, a deal that Oakland declined to match.
At the time, Mayowa had just three starts to his credit but demonstrated serious potential in his limited game film. Not wanting to cap his long-term earning potential, Mayowa’s reps pushed for a clause that would have allowed him to opt out this offseason if he appeared in 60% of Dallas’ snaps between ’16 and ’17. That never became a factor as Mayowa did not blossom as expected.
Mayowa, 27 in August, had just 31 tackles and one sack in his 381 snaps last season.
In a related move, the Cowboys have also cut defensive tackle Joe Vellano. Vellano hooked on with Dallas’ practice squad late last season and re-signed on a futures deal in January.
