The Celtics have the wonderful problem of being "too unselfish."

Chris Forsberg has a great article posted at ESPN.com that highlights the Boston Celtics highly active ball movement we've witnessed during the NBA preseason. It's something that's made an impression on Isaiah Thomas, who's in his first off-season/preseason with Brad Stevens and the C's.

Especially at the beginning of preseason, the teams I've been on it's like, 'Man, we've got to move the ball a lot better,' " point guard Isaiah Thomas said. "This team, that hasn't even been a question. Coach has kind of been like, 'You guys sometimes pass a little too much. You guys are passing up some really good shots to try to be a little too unselfish.' I guess that's a good problem to have.

"Guys are just playing for each other," Thomas said. "I always say that. I think guys are trying to make the game easier for each other and that's the motto of this team -- just, if you don't have a play that you can make for yourself, make one for another guy."

Brad Stevens is building quite the culture in Boston.
