Rugby League, which is by far better supported than speedway, always have play-offs in each of their 3 divisions.
And it isn't guaranteed that the top team win the trophy.......as indeed St.Helens RLFC did this year after being second in their lg table..teams lower than that have won the final in the past.
It makes for a popular and exciting season's finale.
G.B. did of course enjoy some luck in the final race...but they'd beaten Poland in Heat 3 so fair does.
Incidentally I think I'm correct in saying that the 4,3,2,0 speedway pairs format was the brainchild of the late, great, promoter Ian Thomas who introduced it to the second division pairs event so many years back.....and his Comets outfit loved it.
