There used to be an old saying! A bookie was showing a guy around his home town. He pointed to a house on a hill and said, "That's my "parlay" house." Driving a little further down down the road near the beach, he pointed to a house overlooking the ocean and said, "That's my "teaser" house!"
The point is, they don't call them teasers for no reason. As Chuck pointed out, you only need one team to go down the tubes to take you out of all your teasers. For example, this week the Colts are 14.5-15 point faves. You just know everyone is going to load up on the Colts with teasers. Now just suppose the 49ers Smith has a helluva game and the 49er's defense keeps intercepting passes. Colts come back to win but ONLY by 7! Could happen you know! With so many 3 point games on the board, you just know that some teams will win by 10 points or more!
