Delap use to be Javelin champion.
The real record.
Rory Delap served as the inspiration for Danny Brooks, a PE teacher from West Yorkshire who currently holds the world record for the longest throw-in. Brooks teaches at Brooksbank School Sports College in Elland. The record currently stands at 49.78 metres (163 ft).
The flip throw-in could actually be legal, but its never seen in International, Premiership or European football, seems to be an American thing.
