Coaches want Horn. Scouts want Surtain.
Both of them are numbskulls.
There are good quality CBs to be had in the 2nd and 3rd rounds.
Cowboys should be wanting to trade down into the late teens (no later than 20) while getting an extra late 2nd round pick and possibly a late 3rd or 4th as well.
Then use that traded down 1st round pick to go after someone like big interior DT Christian Barmore. If he's taken, Cowboys could also go after either big O-Tackle Teven Jenkins or LB Zaven Collins.
Then pick up a CB like either Eric Stokes, Rodarius Williams, Greg Newsome II or Kelvin Joseph in the 2nd round with 1 of their 2 2nd round picks. Heck, if the Cowboys got lucky enough to see Caleb Farley drop to #44, definitely pick him up at that point.
If the Cowboys use that traded down pick on a OT or LB, they could also use 1 of their 2 2nd round picks on DT Alim McNeill.
The key is to create as many picks in the first 2-3 rounds as possible, especially since those 1st round rated CBs aren't bonafied top 10 overall talents. But knowing this front office, they will continue to bumble things up and make the wrong decisions. It's why they continue to fail to build a playoff winning team for the past 26 seasons.
Oh, well...enjoy your wasted #10 overall pick on either Horn or Surtain. It's only going to leave other holes open and in need for this very bad Defense. The Cowboys front office keeps playing checkers while other teams play chess. Good luck.
