I've had my heart set on Cowboys re-stocking the trenches, DeCastro seems a safe pick, and/or the best DT/DE/OLB available with that first pick.
BUT, I keep saying in all my posts that I think this team needs to get smarter and more instinctive and Safety has been a HUGE weakness for this team for a long time (particularly since decline in production from Roy Williams).
It isn't as sexy as getting some help for D Ware up front, because that was a huge issue last season, and would help secondary overall as well, but adding Barron sounds like it has a good chance of helping in a big way as well.
What is his injury history like, moving forward. I heard he's had a few injuries he's played through over last few seasons. Are they long-term/chronic type problems?
