I have to disagree. More isn't always better. NE is a poor poor example because their success is so closely tied to Brady. Personally, I think that roster would be a bottom feeder without Brady. It's easy to think that their defense is great, but it isn't. They do not spend as much time on the field because Brady will literally dink and dunk for long drives that allow the defense to rest longer.
Don't be fooled by their draft philosophy. They do what they do out of necessity, not because it is the best philosophy. They are consistently in the playoffs and do not get to draft high, therefore for them, increasing numbers by trading down is the only play they have.
The Bills on the other hand have traded up to get better quality. Perhaps this isn't the best philosophy either, but over time, their will be more pro bowl caliper players added to the roster. I think this philosophy creates better long term results.
NE's method works for them but I do not think it is a good fit for us. At least not until we have QB that can depended on the way NE does.
