BOSTON – If the Boston Celtics’ season is a seesaw, neither end is touching the ground. That might change in the next four days.

Boston currently stands in the eighth spot in the Eastern Conference with a 20-21 record. It won six straight games in early January, but it has followed that streak up with four consecutive losses. Now the Celtics are staring down what may be the most challenging weekend of games that is on their schedule this season.
