MLS Cup Final

FC Rocky has a nice write up on the MLS Cup final that was played yesterday. Houston won on penalty kicks after the game was tied 1-1 after 30 minutes of over time. I can't disagree that Houston didn't deserve to win. My question for everyone is what the MLS can do to give teams more incentive to take risks during the first 90 minutes. Neither team seemed willing to risk much during regular time. And that tends to make for a bland game.
