“He’s gotta be aggressive,” Stevens said of his rookie forward.

But Olynyk has been aggressive — especially lately.
....
Stevens even said that he told some season ticket-holders seated next to the Celtics bench before a recent road game to “yell at [Olynyk] if he didn’t shoot.”

....
“I think he’s just getting more comfortable,” Stevens said. “We’re challenging him too.”

As an example, Stevens noted that he recently gave Olynyk an autographed photo of Olynyk’s defense against Butler guard Roosevelt Jones during a game between Gonzaga and Butler last year.

In that game, Gonzaga led by 1 with 3.5 seconds left after Olynyk sank a pair of free throws. But Jones stole an inbounds pass intended for Olynyk, then drove the length of the court and hit a game-winning floater over Olynyk at the buzzer.

With a smile, Stevens said that ever since he gave Olynyk that photo, “He’s been great.”

Olynyk laughed and admitted, “It probably gave me a spark or something.”
