This team is young enough and talented enough and it is great that most of their holes have been filled. I would say they are one year away from making some noise in the playoffs and accomplishing that for the next few years. They have a very good shot at sneaking into the playoffs this year and it should be a solid campaign.
The Bills are FINALLY in a position where they can replace the one or two free agent departures (a couple years from now) with other free agents and draft. It does not look like there are any seasons coming up in the next 3 years where you will see numerous holes in this team. No longer are they treading water and I, for one, am looking forward to these guys competing with just about ANYONE in the league.
Don't forget about those last second free agent gems that are let go in August. A few smaller holes could still be plugged!!
