What happened to our team?

After the bye this team came alive and became as dominant and complete a team as I have seen in a long long time, our offense was moving the ball at will, our defense was making opposing qb's look silly and forcing TO's all over the field. Ever since we played Dallas, a game which came down to the wire despite our ugly ugly play, it seems like our team died. Whatever we had in that stretch is gone. Moving forward, Winston and Koetters ability to revive that will define who the Bucs of the future will be. Either they will continue to be this dead team that I am currently watching, or they will come alive again and be a real player and top tier contender year after year.
