When sports writers break down NFL teams they should state reasons for the team's success OR failure. In Buffalo's case, if the teams is great, it's because ; It's the fourth year for coach, good drafts over that span, emergence of Fitz, unstoppable Fred. Yada yada.
If Buffalo fails; Fitz is inacurate, didn't re-sign D.Bell in off-season, injuries take toll like every year, can't stop run, Stevie drop's ball too much.
This way, the reader get's a better breakdown of a team, and the writer admit's he/she can't REALLY see into the future, but has a grasp of how the process of the building a specific team is going.
