No MLB team will ever have better than 50-50 odds to win it all as the playoffs start.
Bet "the field."
Certainly, the Yanks look very strong right now, and if the pick up a good SP'er, like I'm sure they will, they might look even stronger, but I'm still waiting for them to have a rough patch before the season is over. Then, maybe some will see them as being less invincible.
