Jayson Tatum, Jaylen Brown and the Celtics head into NBA title defense with something to prove
The good: Three and D. The Celtics led the NBA with 1,351 made 3-pointers last year — 140 more more than the next-most chucking team — and they also had the most steals and defensive rebounds. Tatum and Brown are All-NBA playmakers, and Jrue Holiday and Derrick White are two of the best perimeter defenders in the league.
