I think that the Bills are a couple of starters (LB, LDE) away from being a top 5 defense. Jauron has done a good coaching job there. On offense however, there's a long way to go. The Bills still need 3 or 4 solid starters to emerge, including at the most important position: QB. Plus the offensive coaching has stunk over the last 4 years. The Bills keep changing systems and coaches and never get anywhere.
