You can draft your dtackle in the 3rd or 4th round.
Ok. Check this out...
Trade down from the Top 10 into the late teens and secure an extra 2nd and 4th round picks. Use that late teens 1st round pick on a WR who is fast, quick and can gain separation right away at the line of scrimmage. Someone like Texas Longhorns WR Isaiah Bond: 5'11", 180 lbs, 4.28 40 yard dash, great separation WR and a playmaker who has played both for the Alabama Crimson Tide and Texas Longhorns. THIS is the type of WR the Cowboys need on offense...

Then use our early 2nd round pick on DT / DE Alfred Collins. If not, can always risk taking him with our 3rd round pick. I don't believe he will last past the 2nd round, but it's possible he lasts into the 3rd round. Dude is a beast, playmaker and can play anywhere along the D-line. 6'5", 320 lbs, 4.9 40 yard dash...
Then use our picked up 4th round pick on RB Jaydon Blue. 6'0", 200 lbs, 4.40 40 yard dash. Dude has a unique blend of breakaway speed, strength, quickness and burst. Can run both in between the Tackles or outside. Always has the potential to run for a big play. Very similar to Tony Pollard but a little stronger.
