On Friday, we highlighted Boston Celtics rookie Chris Cenac Jr. for his amazing dunk for the G-League's Maine Celtics. But you also can't ignore the game that fellow rookie Dillon Mitchell had in the win over Delaware.

Mitchell, the rookie from St. John's, had 20 points and 10 rebounds. It was his first double-double of the season and it earned him Maine's Player of the Game honors.

Like Cenac, Mitchell has been up-and-down this season between the Celtics and Maine. He's played in only one NBA game, and he has yet to take a shot or record any baskets.

He was taken No. 40 in the NBA Draft out of St. John's. And despite his lack of minutes in the NBA, there is real excitement over his athleticism, which can be an asset on both the defensive side of things and on the glass.

A four-year collegiate player who played at three different schools, Mitchell played an integral role in St. Johns's continued turnaround under Rick Pitino, helping the Red Storm earn a No. 5 seed in last year's NCAA Tournament. The Red Storm also won the Big East regular season and the Big East Conference tournament.

But before he got to Queens, Mitchell began his career at Texas, starting 38 games as a true freshman and averaging 4.3 ppg before scoring 9.6 as a sophomore. He transferred to Cincinnati as a junior, scoring 9.9 ppg before landing at St. John's for his senior year. He averaged 8.3 ppg and seven rebounds while also dishing three assists per game.

He was only a career 19.3 percent 3-point shooter in college. That is something that he's continuing to work on at the pro level, and we've some flashes of improvement in both the Las Vegas Summer League and the preseason.

After being off for several days, the Celtics are back in action against the Dallas Mavericks at TD Garden on Sunday night (6 p.m. ET). That game will feature multiple returns. First, Kyrie Irving will come back to Boston, as he has many times before as a member of the Nets and Mavericks. Then, Cooper Flagg will return to New England for the only time this season.

He's a native of Maine and one of the top players in the league right now.

The reception for Flagg is expected to be extremely positive, while the reception for Irving is expected to be frosty as always.
