I think this is obvious. Don't reach for a player at #10. There is going to be a quality player available. Maybe it is not Farley or Surtain, it will be another player. I do think if all the top players are gone except for the QBs, the Cowboys will find someone willing to trade up. Having multiple 2nd round picks and a later 1st round pick is a better situation than reaching for a player 10 spots to soon. With a trade down they can draft a CB, DT, and LB with their 1st 3 picks.
If Pitts is there at 10 and there are no trade partners and Sewell is gone as well, then I take Pitts without hesitation. Sure the Cowboys have Schultz and Jarwin, but they are just TEs. Pitts is going to be a game changer, a matchup nightmare. I would not take another WR, unless I was willing to trade Cooper (I am but I don't think the Joneses are). And if I do take a WR, he needs to run a legitimate 4.3 40.
