Jayson Tatum has taken a step forward so far this season.

The 21-year-old has gotten off to a monster start for the Celtics, averaging a career-high with 21.1 points per game for Boston. Tatum was the go-to guy for the C’s as they were forced to come from behind to defeat the New York Knicks at Madison Square Garden on Sunday.

Tatum accounted for 30 points in the win across 37 minutes of action, while also dishing out a career-high seven assists. For more on his big day, check out the video above from “NESN Sports Today,” presented by People’s United Bank.
