"According to Stats Perform data, Delap directly assisted on five Premier League goals from throw-ins, and Stoke City as a whole have scored 24 goals from those situations. Since 2008-09, no other player has more than two direct throw-in assists, and no other club has scored more than 12 goals from throw-ins. In other words, Delap and Stoke were at least twice as effective at this aspect of the game when compared to any of their competitors.
Taylor charted all of Delap's throw-ins in his first four seasons with the club, and he found that Stoke scored 25 league goals from throws taken by the Irishman (even if they weren't considered direct assists). In the 2007-08 season in the Championship, a then-31-year-old Delap's throws led to goals eight times -- six of which came while the game was tied. According to Taylor's study, Delap's throws added about six points to Stoke's total, which ended up being the difference between automatic promotion and a spot in the playoffs."
