I did that last year. I think I used 4-2 or something though. Hit enough to make the playoffs
Barring something unforeseen I should be in the playoffs (sitting in a tie for 2nd). I may even pull off a #1 seed with a little luck using this strategy. Although I've been predicting 3-1 every game to friends for about 4-5 seasons in a row it seems. Gets to the point where they ask me "So, what do you think... 3-1 game tonight?"
