The Cardinals have signed cornerback Marcus Williams, according to Kent Somers of The Arizona Republic (on Twitter). Williams finished the 2017 season with the Texans. 
Williams started 15 games in three seasons with the Jets, but did not start a contest in 2017. The Jets shopped him last summer and later waived him in October, leading him to Houston. With the Texans, he appeared in ten games as a reserve and totaled 12 tackles, four pass deflections, and came up with an interception against the Seahawks in a late October game. His most notable season came in 2015 when he tallied six interceptions in 13 games with Gang Green.
Williams will now fight for a reserve job on a cornerback depth chart that is presently headlined by Patrick Peterson and Brandon Williams. If the Cardinals can land an impact cornerback early in the draft, they’ll likely have a rookie starting opposite of P2. Other reserve corners in Arizona include C.J. Goodwin, Ronald Zamort, Jonathan Moxey, Jarell Carter, and free agent pickups Bene Benwikere and Louis Young.
No way Brandon Williams starts
Yeah, he is headlining nothing
