It's somewhat below-the-radar, but one early preseason story worth noting is potential improvement in the Bills offense thanks to new offensive coordinator Brian Daboll.

Buffalo's offense was stale and caveman-like last season when Rick Dennison was the offensive coordinator. Daboll could be the next innovative offensive mind based on his use of formations, designs and personnel groupings to get a stagnant Bills offense, which could have the least talent of any in the NFL, to look sharp during Week 1 of the preseason last week.

The Bills defeated the Panthers, 28-23. Nathan Peterman and A.J. McCarron combined for 16-of-20 passing for 235 yards. Rookie Josh Allen displayed his big arm and wasn't afraid to go deep. The Bills piled up 430 total yards.

Yes, the Panthers played a vanilla game not showing the Bills anything fancy on defense. But the Bills are one of the few teams in the NFL with a wide open starting quarterback battle. Daboll has to find out who his No. 1 man is going to be so expect the Bills to continue to open up their playbook and attack downfield.

Cleveland has two good quarterbacks to use, Tyrod Taylor and Baker Mayfield. Expect Mayfield to continue to see a lot of action. The first overall pick in the draft played well in the Browns' opening preseason victory against the Giants completing 11 of 20 passes for 212 yards and two touchdowns. The Browns are deep in receiving talent and the Bills are weak at linebacker, both starting-wise and depth-wise.
