No offense, unless one of the top QB's falls in your lap. Then take him and use him as a chip for the future and against injury.
No LB at 10 unless you think Parsons or Collins is a MLB. I don't think either is a Mike, and IMO you need to move LVE to Sam and Smith to Will.
(LVE tends to lead with his head when he tries to stack and shed -- will always end up injured at Mike, Smith runs around blocks causing lanes - he needs to shoot gaps and chase)
No S that has the talent to be taken at 10 -- but you need to look in the 2nd for one for sure.
No DT at 10 rates anywhere near high enough. Alim McNeil in 3rd would be perfect imo, with Brown taken with comp 4.
No DE as you have a TOP 5 paid DE in Tank, Gregory, and two young DE's. Yes get a high upside developer round 5-7, but not at 10.
Dallas needs a CB. As long as Surtain or Farley are available at 10 -- pick one of these two.
If you can get a starting CB at 10, starting FS in 2nd, starting 1T in 3rd, legit MLB like AJ Britt or Buddy Johnson in the 4-7 range (to compete Gifford, Bernard), as well as add development 1T in Brown, and another development DE --- the rest of the picks wouldn't matter too much and you would be well on the way to "fixing" the defense.
