from my experience the best teaser stratagy is to tease a 7 1/2, 8, 8 1/2, 9 or 9 1/2 favorite down. you get a supposedly superior team at under a field goal. if you gotta guy where ties do not lose....you can tease add a 10 point favorite.....these are all assuming you are playing 7 pt teases....if not adjust accordingly
