When the Jaguars get back on the field Monday for the start of OTAs – the first time rookies and veterans will work together – one of the players to watch will be rookie cornerback Trey Wilson. Wilson, an undrafted free agent from Vanderbilt, was impressive during last week’s rookie camp even though he was playing a new position. Before arriving in Jacksonville, Wilson was told by defensive backs coach DeWayne Walker that he would be working as the nickel cornerback covering the slot receiver. “It’s new territory for me but I’m adapting to it well,” Wilson said. “Coach Walker did a good job of teaching the techniques and the scheme.” Wilson is 5-foot-10 and 193 pounds, the type of build the Jaguars require from an inside cornerback. Although the space appears to be more confined inside, Wilson said: “There’s actually a lot more space and the receiver can go inside or outside. And the throws are quicker. But playing in the SEC has helped me.” The Jaguars signed veteran cornerback Marcus Trufant on Tuesday and he will compete for time in the slot.
