It is interesting how this draft is working out. After Sanders' stock fell out of the top 3, the value of pick #4 dropped. It doesn't feel like there will be a player left who is worth a #4 pick. I am not sure I am that worried about it. So you take a player at #4 and it is "graded" a reach but if the same player went say #8, it gets an A?
I bet if you looked back at drafts, that the average performance of #4 picks is not that much different than the average performance of #8 pick (for example).
What is important is to figure out who the best player is. Make a good pick at #4 and you will be fine, make a bad pick at #4 or #8, and it hurts.
