Jaylen Brown isn't a happy camper right now for the Boston Celtics. The Cs lost another game on Wednesday against the Atlanta Hawks as they finish their road trip 0-3.

Brown is clearly unhappy with his team's current slump and firmly believes that Boston can do so much more.

“As long as you got that Celtics jersey on, you should never be comfortable with losing,” Jaylen  Brown said after the Celtics' 127-112 loss in Atlanta via A. Sherrod Blakely of Bleacher Report). “We've had the opportunities (to win) and we haven't…I can tell the mental focus, it's not there. It's not enough. I don't know. We have to be better going from game to game; have the right mentality. It's tough but we have to do it.”

It clear that Brown and the Celtics haven't been sage-ing enough as of late to get the bad vibes out. For the first-time All-Star, their last three games have definitely been very winnable; unfortunately, the effort hasn't been there.

They Celtics were up as much as 24 points against the New Orleans Pelicans last Sunday but still lost 120-115 in OT. This tough defeat was followed by another one, as Luka Doncic hit back-to-back threes in the dying seconds of Boston's visit to the Dallas Mavericks to hand them a 110-107 heartbreaker. On Wednesday, they were victims to a red-hot shooting evening from Danilo Gallinari after the 32-year-old vet torched Boston with a career-high 10 threes en route to a blowout loss.

Almost halfway through the season, the Celtics have looked quite different from last season's squad that was two games away from booking a trip to the NBA Finals. They're now hanging on for dear life at the East's eighth spot with a 15-17 record, with the New York Knicks and the Charlotte Hornets breathing down their neck.
