If defense needs have a higher grade 1st 4 rounds, I go defense.
These days, due to free angeny and salary caps, needs. change rapidly. However, I beleive a team should draft a great value when the opportunity rises regardless of present need.
Perhaps I should word this better. I the Cowboys should have the opportunity to draft a QB that they evaluated as one capable of playing at a high level for a great value then they should do it rehardless of other needs.
The idea of "needs" should never suggest that a particular player satisfies that need. That type of mentality does not recognize the reality of potential failure or injury. The correct approach should be the desire to strengthen a particular unit. That implies that few squads are perfect, that they can't use an upgrade of some degree.
Prioritizing can result in a loss of value or quality and again, we never know where a need is going to appear.
For example, at the beginning of last aeason we thought we had an elite LB squad.
