Buster Skrine isn’t running faster. He’s not in better shape. His technique hasn’t changed. But he has been an improved player lately, and it isn’t a coincidence. “The difference is I’ve just become a smarter player,” the Jets cornerback said Thursday. Jets coaches have raved about his performances recently, head coach Todd Bowles saying he has “played outstanding football” over the last three weeks, and Bowles rarely throws around compliments. “He’s just really turned up his play,” defensive coordinator Kacy Rodgers said. “He’s locked in.” The versatile Skrine, in his third season with the Jets, was particularly impressive in Sunday’s loss to the Saints, notching a team-high grade of 88.2 by Pro Football Focus, forcing and recovering a fumble, notching five solo tackles, and allowing just 38 yards on nine targets. He had a 81.3 grade in the upset win over the Chiefs on Dec. 3, and has produced 52 tackles, an interception and eight passes defensed this year, the best numbers of his Jets’ career.
