Grant Williams and Tacko Fall, the best of friends

The Boston Celtics draft-class bro-mance has added a new chapter thanks to Grant Williams' Instagram story Sunday. He posted a video with Summer League teammate Tacko Fall demonstrating their new friendship, according to a tweet by Twitter user "Zach".

Both Williams and Fall went to Fenway Park in Boston to take in a Liverpool versus Sevilla soccer match, as's Celtics News tweeted out.

Williams then confirmed his appearance at Fenway with this tweet:

Their kind of wholesome friendship is exactly what this team needs this upcoming season, now we will have to wait and see if Williams can generate this kind of relationship with the rest of the roster.
