Those three, of course, are Jourdan Lewis, Chidobe Awuzie, and Xavier Woods. That fourth defensive back, however, should not be forgotten about as we enter the beginning stages of the 2018 season. That player is former Florida State cornerback Marquez White.
Rather than playing alongside his rookie counterparts in the secondary, White spent time on the Cowboys practice squad in 2017. The former sixth round pick was signed to a futures contract at the end of 2017, however, and now has a chance to compete in camp once again.
Entering their sophomore seasons the starting secondary already appears to be taking shape. Chidobe Awuzie and Byron Jones are just about locked in to the outside cornerback jobs, Xavier Woods is expected to start at safety beside Jeff Heath, and Jourdan Lewis is battling with now third year player Anthony Brown for the slot corner role.
So where does Marquez White fit into all of this?
Well, the aforementioned players are locks to make the 53-man roster, but Marquez White should be the favorite to win the 5th cornerback spot going forward. White's raw talent is undeniable, and he has the ability to play under both man and zone responsibilities.
The main reason we should be optimistic about Marquez White's chances to land on the final roster, however, is his athletic profile. At 6'0″ tall, just under 200 pounds, and long arms White fits the mold for what new secondary coach and passing game coordinator Kris Richard tends to look for in his cornerbacks.
And, for better or for worse, Richard clearly values these measureables highly. This is evident in how second year corner Jourdan Lewis has been used thus far in mini camp and offseason activities; being relegated to second team and the slot rather than allowed to compete for an outside cornerback job with Awuzie and Jones.
So with the arrival of Kris Richard, the departure of Orlando Scandrick, the underwhelming play of Anthony Brown, and the raw talent he already possesses, Marquez White has a very strong chance of making the final 53-man roster in Dallas.
