Kelly Olynyk entered the league praised for his smarts and his skills on offense. He learned the game from his father, Ken Olynyk, who was head men’s basketball coach at the University of Toronto from 1989 to 2002. He was also the coach of the Canadian junior men’s national team from 1983 to 1996.

The Celtics big man is not the most athletically gifted player and overcomes that by having a high basketball IQ. His moves are refined, he’s adept at creating space for himself around the basket and he has soft touch.

Per espn.com, Olynyk averaged 8.7 points and 5.6 rebounds as a rookie. He shot 35 percent from beyond the arc as he worked to expand his range. Like most rookies, he largely seemed like a player who was feeling out the NBA game.

Now, in his second season, he is a far more aggressive player and seems to have figured out the philosophy that works best for him. He is thriving in a role off the bench and despite not being a starter, is averaging 25 minutes a game, five more than he played as a rookie.

One of Olynyk’s strongest attributes is how active he is without the ball. He is hardly ever stationary. He does not spend much time posting up. In Monday’s game against Philadelphia, he had a career-high 30 points and none of it came on post ups.

For a big man, he is a skilled cutter and his soft hands allow him to catch almost anything that is thrown his way. He is also shooting 41 percent from three-point range, which has allowed him to primarily hover around the perimeter, where he’s either setting screens or darting to the basket.

You would think the amount of energy that Olynyk is exerting at the offensive end would cause his defense to suffer. However, according to NBA.com, his defensive rating has gone from 105.1 to 104.4. A small improvement but one that has been noticeable. No one will ever confuse him with Joakim Noah but the fact that he is also developing on defense is encouraging.

Olynyk’s evolution from being a passive player to an aggressive one has been one of the better developments for the Celtics this year. As he continues to grow his all around game, his future looks tantalizingly bright.
