Videos of the plays   These are the top 15 plays through the first 10 weeks of the 2015 season that had the largest single impact to Pro-Football-Reference’s win probability, which is intended to be a measure of a team's chance of winning the game after every play of the game, based on the line, current score, and current field position.   The #1 play doesn’t make a lot of sense to me as I would expect that play to be comparable to play #5. Regardless, I think this is pretty interesting information.   Rank| Change in Win %|Play :--|:--|:-- 1|72.8%|Patriots’ Stephen Gostkowski kicks game winning fieldgoal 2|68.4%|Matt Forte’s go ahead 7-year touchdown pass 3|61.8%|Titans’ Jalston Fowler injured after failed 2-point conversion attempt 4|60.2%|Broncos’ fumble six for the win 5|56.5%|Jaguars’ Jason Myers hits game-winning 53-yard field goal 6|54.7%|Olsen’s game-winning TD grab 7|54.3%|Packers’ failed two-point conversion in the last 32 seconds 8|51.9%|Alford’s game-winning pick-6 9|51.6%|Kam’s knockout punch 10|49.4%|Bears’ Robbie Gould kicks game-winning field goal 11|47.5%|Broncos’ Chris Harris Jr intercepts pass for TD 12|47.1%|CJ Spiller’s 80-yard TD for the win 13|46.9%|AJ Green’s 80-yard explosion 14|45.9%|Witten for the win 15|45.8%|Saints’ Drew Brees ties NFL record with 7th TD pass
