White's play had been questionable before the Commanders' game, as in the first two games of the season, he would be a part of lots of missed tackles turning into more yards, and being beaten on some plays that did or almost resulted in big receptions. Fans speculated that White has never been the same since his ACL injury.
White would lock down Dotson and McLaurin in his third game of the season, allowing three receptions for 19 yards and recording a diving interception in the end zone.
White and Benford are in similar situations preparing against the Dolphins, though White would be more trusted in playing man against Hill or Waddle compared to Benford, but due to both of their speed, there's probably going to be little man played from even White.
Overall expect a lot of zone and very little man from both of these corners.
