my playoff betting strategy turn 1000 into 100,000

ok so heres a strategy for the playoffs pick a series in which you think you can choose who will win and in how many games so last year for example i would have said miami in 6 over indiana so then you would put 100$ on each winning combination (only 10) for a six game series doubling each win if it goes 6 games and miami wins your 6-0 (6400 up) then all you have to do is pick four straight games in general any sport or even next season then you would be 10-0 and turned 1,000 into 100,000. what do you guys think of this .

theres only 10 winning combinations for a 6 game series and 20 winning combinations for a 7 game series .

good luck going 10-0

ok so i went back and did some research and i isolated it down to 5 five series that go six games and 9 out of the last 20 years its been the lower seed team beating a higher seeded team in six its either the 4-5 series on east and west coast , or the semi finals the underdog wins in six of the finals the underdog wins in six, so now you have your 6-0 now all you would have to do is go 4-0 for next season 

typo 9 out of the last 10 years
