Mac Jones acknowledged struggles as the New England Patriots transition to a "new offense," but expressed confidence that things will turn around.

"I'm going to figure it out. I always have. I always will," the second-year quarterback said. "At the end of the day, you're going to have your ups and downs with anything new ... I think we're close on a lot of things. It's just that 2% we need to fix."

Jones' remarks came a day after the offense had arguably its worst practice, filled with numerous breakdowns. 

Bill Belichick, who has said he's spending more time with the offense this year than he has in the past, hasn't named an official coordinator to replace Josh McDaniels, who is now coach of the Las Vegas Raiders.

"It's just getting the communication down," Jones said. "It's different than what we've done in the past. It's a little frustrating sometimes, but our offensive line -- the players and coaches -- are trying the best they can. I have all the trust in the world in those guys ... It's not going to happen overnight, but we're going to grow."
