Baker Mayfield offered optimism. Nick Chubb provided brutal honesty. Regardless of the lens through which anyone views the Browns' offense, the unit desperately needs quick improvements because the Cincinnati Bengals will visit FirstEnergy Stadium on a short work week for the home opener Thursday night. In their season-opening 38-6 loss to the defending AFC North champion Baltimore Ravens, the Browns scored the fewest points in the NFL and ranked 24th with 306 yards in Week 1. “Obviously, there's a ton of room for improvement,” Mayfield said on Zoom before Tuesday's practice. “It's not just false hopes. It's there.”
