Will the Buffalo Bills be better on offense and defense than they were last season?

Once again, the Buffalo Bills added numerous new faces to the roster. Due to players leaving in either free agency, retirement or trade, the roster to start the 2018 season will look very different from 2017. With the changes to the roster, the performances on both sides of the ball could be noticeably different from the previous season.

Offense

Two members of the starting unit on the offensive line decided to hang up their cleats and call it a career. Ryan Groy has the best opportunity to be Eric Woods replacement and Richie Incognito’s replacement is still unknown. The offensive line could take a step back this season.

After trading Tyrod Taylor to the Cleveland Browns, it was made loud and clear that the Bills were going to put all their chips in one of the rookie quarterback’s basket. Josh Allen, of all the first-round caliber quarterbacks in this years draft, might need the longest amount of time to turn into the franchise quarterback the Bills have longed for. AJ McCarron is likely to be the starter to open the season and he is just as much a question mark as Allen is.

The Skinny: The Bills offense got worse over the offseason in vital areas and it wouldn't be shocking to see regression from an uninspiring 2017 campaign.

Defense

The Bills secondary was the strong suit of the defense last year while the front seven wasn't at their best. They struggled to get to the quarterback and generated little to no pressure in the majority of their games. The additions of Star Lotulelei, Trent Murphy and rookie third-round pick Harrison Philips, the front four went under restoration. Shaq Lawson will look to come back strong from injuries over the past couple years. Preston Brown leaving in free agency would have been a blow if it weren't for the addition of Tremaine Edmunds, a more versatile player at the middle linebacker spot. Although they lost E.J. Gaines to free agency, they replaced him with a veteran in Vontae Davis and the starting four in the secondary shouldn't lose a step.

The Skinny: The Bills added depth and talent to the front four and got more athletic at linebacker all while keeping the majority of the secondary talented. The defense kept the Bills in a lot of games last season and on paper they have only gotten better.
