The intersection of value and need is a seemingly delightful thing in many aspects of life.
Your toaster stops working, but there happens to be a huge sale on toasters. Great! Just make sure to read the reviews and ensure it really is a good deal.
Applying this notion to the NFL Draft has similar principles with larger consequences. Teams that find themselves with holes at certain positions are often delighted when April rolls around and the draft is strong at that position.
Again, though: They have to do their homework and make sure it's really a good value and not just a perceived one that fills a need.
