perfect example of what I have discussed before. Do you need talent at the WR and TE spots? Yes. Do you have to get them in the top 5 picks - no. History bears this out repeatedly. Look at your list above and how many of them were 3rd and 4th rounders or mid first round picks. Trade back to 6-8 and take Pitts who is a monster and matchup problem and garner an extra first or second rounder.
I like this line of thinking. I'm in line with that stance, but what if Smith is Calvin Johnson sitting at 3 in disguise? Makes me pause.
