In the NFL there is a reality of sorts, you can never have enough defensive backs.
That reality came to fruition for the Arizona Cardinals in 2016, as they saw their corner and safety depth chart extensively tested due to injuries throughout the season.
It would make sense then that the Cardinals would like to avoid a similar issue in 2017, so they are looking into the draft to continue to build that depth at corner.
It has started with the Arizona Cardinals putting Teez Tabor through a private work out according to Josh Norris of Rotoworld:
There is no denying Tabor's ability to be a physical, sticky corner, something you are always in need of.
However, concerns over Tabor's ability to cover deep were not helped by a very average combine.
That doesn't concern teams though, as much as his off field and even combative personality on the field.
Tabor has a failed drug test on his record and has been suspended for an incident with a teammate at practice.
The Cardinals likely have more questions regarding the tussle with a teammate and his drug tests than what he can do on the field.
However, you wonder if there is a concern with Tabor's ability to play in man against receivers that can take the top off a defense.
I would wager though, that is not what this private workout was about.
