The Celtics are going to measure their progress this season in small ways — like Phil Pressey’s comfort level not only with his backup point guard duties, but as a shooter.

The Celtics rookie enjoyed one of his most prolific bursts last night in the second quarter of a 109-96 loss to Portland, hitting the fourth and fifth 3-pointers of his NBA career in a 1:26 span.

He’s getting a better idea of how to heat up after coming in cold.

“You have to think about getting your legs into your shot when you’re coming off the bench,” said Pressey. “I’ve been working on that, sitting down and then getting up and shooting right away.

“We had a mismatch today with Gerald Wallace in the post, and they helped off of him,” he said. “I’ve got to take that shot when they help off of him. It’s something I work on every day in practice and the shots went down. Gerald is a willing passer. Whenever he has two guys on him he’s going to find the open guy.”

No turnaround time

Brad Stevens’ first NBA season predictably has been stuffed with new experiences and fresh ways of doing business.

But perhaps the most altered process, especially in a November that features 19 games in 30 days with six back-to-back swings, is the scouting.

There isn’t much of a turnaround for preparation.

“The scouting process has been good,” said Stevens. “It’s been good as far as getting the right amount of information before every game. It’s a quick turnaround, no question about it, and in the first 10 games we’ve only played one team twice, and one other team we had played in the preseason, so you didn’t have much.

“You don’t know a lot about these teams prior to the first time you view them, so it’s a learning curve,” he said. “You can’t quite get in depth as much as you can in college with your team, just because you have a one-day turnaround. The first time the whole season when we have two days before a game is upcoming against Houston (next Tuesday). We haven’t had any time to prepare other than what we do in a walkthrough.”

The Celtics coach finds himself giving thanks for the added resources that come with an NBA team.
