On a short-yardage play this past Sunday, Leonard Fournette took a pitch and before he could reach the line of scrimmage he was met by four New York Jets defenders. With nowhere to go, Fournette was dropped for a four-yard loss on the third-and-1 play that came on the Jaguars’ opening drive of the third quarter. Although Fournette gained 86 yards on 24 carries in the 23-20 overtime loss to the Jets, he hasn’t had much luck on third-down plays and neither have the Jaguars. Since Week 1, Fournette has not converted a third-down play into a first down on three tries. And the Jaguars (2-2) rank 29th among the league’s 32 teams in the NFL on third-down conversions at a 30.8 percent (16 of 52) success rate that they will take into Sunday’s game against the Pittsburgh Steelers (3-1) at Heinz Field. The league’s average third-down conversion rate is 39.4 percent.
