Boston Celtics

The Celtics refused to slow down on the first day of practice

Either they're really hard workers, or they just don't understand percentages.

The Celtics begin training camp this week, and there’s an excitement around the team that’s been building since Isaiah Thomas arrived via trade in February of 2015.

Al Horford joins the team via free agency, Jaylen Brown headlines a deep rookie class, and players like Jae Crowder, Marcus Smart, and Terry Rozier are sure to keep getting better.

The energy was so strong, in fact, that the Celtics couldn’t follow Brad Stevens’ instruction to take it easy as they began walking through the playbook.

According to the Boston Globe, Stevens told the team to give about “30 percent effort” during the exercise, but his team went hard anyway.

“If that was 30 percent, we’re going to be able to fly around,” said Stevens after practice. “I think it was just a misjudging of what 30 percent is, but they were flying early on in practice.”

Every coach wants their players to follow instructions, but in this case Stevens can’t be upset at having a team with hard work in its DNA.
