Heading into this season, not too many people believed in the Boston Celtics. They’re 29-17 entering Wednesday’s home game against the Atlanta Hawks, just a few wins off last year’s pace.

The Celtics are about to get Tatum back soon, too, at which point they could really take off. As good as they’ve been this season, there’s a chance they still haven’t played up to their full potential yet.
