It's a clash of Eastern Conference playoff hopefuls when the Boston Celtics (36-27) host the Atlanta Hawks (29-31) on Tuesday evening. Boston sits in sixth place in the East, while Atlanta is in play-in position as the current No. 9 seed. Atlanta, however, appears to be heating up as it has won three of its last four -- including impressive victories over the Cavaliers and Raptors during that span. John Collins (foot) is doubtful for Atlanta, while Lou Williams (hip) is out.
