This should not be an issue for the Bills, but once again they create an issue.
You cannot rebuild every unit every year.
example....Seattle has kept the majority of their D backs in tact through out the past 5 years and worked on other areas each season.
We had a good D back field coming along and suddenly we now have only of the 4 left. regardless of reason (salary or injury) you must keep your strengths to allow you drafting and focus on your weak areas. 3 years ago we had so many up and coming wide receivers and tight ends we cut people like Hogan and lost Chandler and started playing with a strength position to the point we were so desperate we had to pay Harvin $2m for 6 catches (as I recall). That took time away from working omn other weak areas.
Last year RB was a strength of this team. Now we rip it apart and spend countless amounts of energy and perhaps a draft choice that needs to be spent elsewhere.
We are doing the same with LB's rather than working on the created wideout weakness and the Oline.
These constant efforts to destroy your own strengths come at great costs. 17 years no playoffs.
