Not at all, I'm actually a big Mazi supporter and think he ends up a really good player for this team. My issue that the Cowboys free agency failure has put them in a position where they basically have to hit on multiple starters in this draft. If you need plug and play type starters trading back multiple times is not a great strategy. I wont bash yesterdays trade because they got good value and a guy who fits the bill physically. Personally its not the move I would have made simply because I think Barton is a plug and play C right away.
Even 3rd round picks fewer than 20% of players drafted see 2nd contracts from the team that drafted them. Only about 10% of 3rd round picks will see a pro bowl their entire career, and about half of these guys are out of the league completely by year 4. The vast majority of guys after round 2 are career backups and situational guys. Not a bad thing, don't get me wrong, but this team needs guys who can compete for time at LB, C, RB, DT and a couple other positions to a lesser extent. You can find these guys in rounds 3-4 but it's tough to do.
