I regularly hear that teams should draft for need to shore up the weaknesses on their rosters. For example, I hear that we shouldn't draft Howard because we have Brate. I also hear that we don't need another top WR, because we have Evans, etc.
When is the time to add to a position of strength to overwhelm an opponent? For instance, adding Howard to Brate, adding Davis to Evans, or adding Caleb Brantley to McCoy, instead of filling holes?
Is a team better if it has all holes filled to a respectable level, or are they better if they have a couple of dominant positions of strength with a couple of sub-par positions?
Discuss.
(Btw, only talking about adding to positions of strength when another position is available to fill. Obviously, we shouldn't add a top QB, since he won't get on the field.)
