First FG, Dolphins get the ball at their own 40, go on a 10 play drive (in which they D gave up plays of 20 and 19 yards--the latter on a 3rd and 19). kikced a 40 yard FGH.
Second FG (after Josh INT), the Dolphins began at the Bills 48. They would get 2 more 1st downs and 18 more yards on 8 more plays to get to the 30---and it was still a 48 yard FG.
Third FG FG, after a Bills punt, Dolphins return it 50 yards to the Bills 27. Despite moving back to the 32 on a penalty (would have been a 50 yards FG), the Bills gave up a 13 yards pass play to Hill. Now it was a 37 yard FG
