The Redskins then drove to Miami's 43-yard line, and once again tried to fool the Dolphins with a trick play, this time a flea flicker. Riggins took a pitch from Theismann, ran up to the line of scrimmage, and then pitched the ball back to Theismann, who then attempted to pass it. But this time Miami was not fooled, and Lyle Blackwood made a diving interception at the 1-yard line (making this the first Super Bowl to ever have three consecutive drives end with interceptions). However, Blackwood's interception turned out to be somewhat beneficial for the Redskins, as it pinned Miami back at their own 1. The Dolphins could only gain three yards with their next three plays, and Washington ended up getting the ball back with great field position on their own 48-yard line. The Redskins ran three plays to reach Miami's 43-yard line, but then faced a fourth down with one yard to go. Instead of punting, the Redskins decided to gamble and attempt to get the first down with a run from Riggins, but Riggins did a great deal more than pick up the first down. Coach Joe Gibbs called his trademark play I-Right 70 Chip, starting tight end Clint Didier in motion towards the right, then reversing motion back to the left. The idea behind the play is that the Redskins' line and skill players (except for Joe Theismann) would combine to block everyone but the smallest cornerback whom the defense had on the field at the time, with the notion that John Riggins would be able and ready to break the tackle of that player (in this case, it was Miami cornerback Don McNeal). Theismann handed to Riggins, who blasted through MacNeal's arms right at the line of scrimmage and still managed to build up enough speed to outrun defensive back Glenn Blackwood for a 43-yard touchdown run, giving Washington their first lead of the game, 20–17, with a little more than ten minutes remaining. McNeal, who was assigned to cover Didier on the play, slipped briefly as Didier changed direction. The Redskins ran the play to the left, behind Didier and fullback Otis Wonsley, and Riggins ran over McNeal to score the touchdown. Although McNeal did indeed slip briefly while following Didier across the formation, it would have made little difference in the outcome of the play. Despite a valiant effort by McNeal, the
