The Boston Celtics through 52 games have a 37-15 record. That's good enough for the top spot in the Eastern Conference. Only the Golden State Warriors and Houston Rockets out west have better records. Brad Stevens led the Celtics past the 50 win mark last season. Can he surpass 60 wins this season? Based on the team's winning percentage the Celtics are on course to finish with 58 wins, so it's definitely plausible.
The last time the Celtics hit the 60 win mark was during the 2008-2009 season. They started that season extremely hot and were looking like the favorites to repeat as champions prior to the Kevin Garnett injury.
