I understand your point but I'm pretty sure you really don't think that's what he's saying.
There is no doubt they botched the first two rounds that year when they moved up for Claiborne. It was a bad decision. He isn't a good player. However, the fact that we're focusing on the only early pick that Dallas has missed on since 2009 says an awful lot about how well they've been drafting. Dez, Tyron Smith, Travis Frederick, Zack Martin, Terrence Williams, Sean Lee, Demarco Murray, Wilcox, Hitchens, Etc. They've been drafting as well as any franchise and have probably done better than anyone else with undrafted free agents.
The logical choice when looking at the acquisition of college talent is to look at the entire rookie class... including UDFA's. Since Garrett took over, the Cowboys have done as well as any franchise in acquiring college talent.
If you want to be unhappy about getting Claiborne, then I understand. I'm not happy about it either. However they've been doing exceptionally well with college players and it seems disingenuous at best for anyone to just say that draft was a bust and not talk about how well the team has been doing overall in finding guys, regardless of round or UDFA. And like he said... the draft used to be longer and guys like Beasley would have been part of the draft until recent times.
As an aside, as I type this on the NFL network they're saying that Bobby Wagner is maybe the best ILB in football. That is who Dallas would have taken in the 2nd round had they not traded up for Claiborne. It is a missed chance to get a very good LB and it points to how well Dallas has been doing identifying talent... as does Michael Brockers, the other guy Dallas would have taken had Claiborne not happened.
