‘The 4-3 defense gives the Bills flexibility in looking for solutions. An undersized, 245-pound defensive end can serve as a situational pass rusher. Whether it’s an undersized, 245-pound defensive end, a 260-pounder who spent most of his time at linebacker in college or a 285-pounder, it doesn’t really matter. The Bills’ challenge this offseason is to find a good one (or two) and utilize him in whatever way works best — standing up or with his hand on the ground; on the line or at linebacker.’
