It is not easy to go on a long winning streak, and even harder to pull one off that manages to go into double digits to start the regular season. The Cavs have roared out of the gate to do both, causing NBA fans and analysts alike to begin asking if Cleveland is really a legit threat to Boston in the East.

Jayson Tatum was one rebound shy of a triple-double in Boston's 139-114 win over Brooklyn and one assist shy in Saturday's 126-123 overtime victory over the Raptors. Toronto needed that travel call on his game-winner at the buzzer right then and there, not in the Last Two Minute Report.

The Cavs are the fourth team to start 15-0, joining the Golden State Warriors (2016), Houston Rockets (1994) and Washington Capitols (1949). The Warriors set the league record by winning their first 24 games on the way to a 73-9 season.
