Boston Celtics guard Terry Rozier was not a happy camper following his team's preseason loss to the Cleveland Cavaliers on Saturday. Following the loss, the 24-year-old did not hold back when asked about his team's performance, claiming that the Celtics currently do not have the right type of mentality to compete at the highest level.

Rozier, who was arguably the Celtics' best performer on Saturday with 17 points on 7-of-17 shooting, one three-pointer, two rebounds, one steal, and zero turnovers in 26 minutes of action, shared how he thinks his team is not yet mentally prepared for the upcoming season.

“I feel like we need to get our mind right. Take some time off,” Rozier said, per Taylor C. Snow of Celtics.com. “But at the same time, we gotta get out there and just find our way.”

Following the 102-113 loss at the hands of their rivals, Rozier blasted his team's brash mindset.

“I feel like we arrived like we already won something,” he added. “Teams know that people are talking about us every time you turn on the TV, so that’s going to motivate them to want to beat us no matter if it’s the second string, third string, no matter who it is. We’ve got to stay grounded and go back to playing Boston Celtics basketball and being who we are instead of thinking we’re above everybody.”

Rozier was practically a nobody prior to his breakout campaign last year. Nonetheless, he has no intentions of sitting on his laurels after a historic season and hopes that his team will have the same type of mentality entering the new campaign.
