Obviously there are teams that are better at defending the four wide than others, but I don't think it is a matter of not 'catching up' with the four wide look by failing to implement nickel, dime, or quarter defenses. Some teams obviously have nickel, dime, and quarter packages but most teams will simply adjust their base defensive gameplan to account for a four wide look (i.e. blitz and stunt, zone defense). And it comes down to who you play too, more run teams on the schedule, less work on spread defense. I think it is all about personnel. The better your personnel, the more flexible you can be with your defensive gameplan.

I feel like I just sounded really stupid there, but I don't really understand the OP.
