Become a $5,000 sponsor to benefit the Boston Celtics Shamrock Foundation, and you and your team of five will shoot from four different spots on the TD Banknorth court to compete with other teams for the grand prize of an away game trip with the Celtics. The top four teams will receive tickets to Sunday's game against the Hawks and the top two will battle each other at half time at the game that night for the grand prize of an away game trip with the Celtics. The donation goes to a good cause, and you'll also get guided tours of the locker room, a celebrity shooting coach, breakfast in the Legends restaurant, and Celtics gear.
