Antonio Cromartie has played for a lot of great defenses.
In New York, the Jets rode a stringent defense to consecutive AFC championship game appearances in 2009-10, with Cromartie playing a part of the second team.
Darrelle Revis, a three-time All-Pro, manned "Revis Island," while Cromartie, another All-Pro cornerback, lined up on the other.
The Arizona Cardinals made a splash when they signed Cromartie in the offseason. He thinks this Cardinals secondary could become better than any he played for in his eight-year career.
"It's probably the most talented defense, No. 1 secondary that I've been around just from the talent standpoint," Cromartie said on the Bickley and Marotta show on Arizona Sports 98.7 FM.
There's a lot to like about the Cardinals' defense with the veteran Cromartie and Patrick Peterson, a two-time All-Pro who is just 24 years old, in the secondary.
The team's safety position has ability just like the cornerbacks, but carrying a few more question marks. Tyrann Mathieu is coming off an ACL tear and Deone Bucannon is a rookie.
Just because the defense has talent, it doesn't mean that all the potential has been tapped.
"Experience-wise, I think it's different," Cromartie said. "Having Darelle on one side, myself as veteran players, having (safeties) LaRon Landry to Eric Smith on the backend, just the experience standpoint, I will have to say we are ranked No. 2 from that standpoint."
Additionally, according to Cromartie, talent won't win championships; the team that plays the best collectively will.
