1. Isaiah Dunn, CB, NY Jets
Undrafted rookie Isaiah Dunn was given a golden opportunity on Saturday when he earned the start with Blessuan Austin out for personal reasons.
It was a major bode of confidence in Dunn given how well sixth-round pick Brandin Echols had played this summer and considering the fact that Dunn had only recently returned from injury.
Unfortunately, Dunn didn't exactly make the most of his opportunity.
The Packers picked on him early as Dunn was targeted five times on the first three drives. He was tagged with allowing three catches for 41 yards, per Pro Football Focus.
Not ideal given that he was going up against Green Bay's second and third-string wide receivers with Kurt Benkert throwing the ball.
Dunn has been one of the pleasant surprises of the offseason and is very much in the mix for both a roster spot and a starting job. Although it's hard to see him earning the latter after his performance this past weekend.
In fact, he's hardly guaranteed a roster spot either with Bryce Hall, Austin, Echols, Jason Pinnock, Javelin Guidry, and Michael Carter II all probably locks for the 53-man roster.
Dunn needed a strong showing on Saturday to convince the Jets that he deserves a spot on the team and in the starting lineup.
But his poor performance could have ultimately cost him both.
