Player: Xavier Williams

Position: Nose tackle

College: Northern Iowa

Height: 6-foot-2

Weight: 309 pounds

Stat to know: In his senior season, he had 93 tackles and eight sacks and was an FCS first-team All-American.

Road to the roster: Williams' toughest obstacle will be his height. At 6-2, he’s not the ideal size for a nose tackle but Williams has built a career on proving people wrong. The Arizona Cardinals have added significant depth on the defensive line, which might land Williams on the practice squad. His stiffest competition will be Alameda Ta'amu. If he can prove he’s a better than Ta'amu, Williams has a shot to be a Cardinal.
