Over the past 5 drafts the Cowboys have used picks 34, 34, 40, 47, and 60 in the 2nd round.
For a variety of reasons, they won't get a single snap from any of those picks for the first 4 weeks of the 2016 season.
Your point is taken, but you've definitely gone a year too far. Including 2011 completely skews the reality of your numbers. I've tried to establish the idea that after that original 4 year period is over, you can't really consider a player anything more than a free agent outside of the fact that you may be more familiar with the player and know whether they fit in your system.
As for them missing out the first 4 games, that's simply a coincidence.
If Gregory can stay out of trouble, and I'll concede that is a big if at this point, that pick may very well turn out well. Lawrence, I'm still not sure what the story is here, but he has at least shown he can perform. I think you have one truly questionable pick with Escobar, but Jaylon Smith is a great pick.
The questionable nature of our drafts I think are what we've done in the 3rd round more so than the 2nd.
The 4th round has been almost a complete waste as well. I think they take too many project players in the 3rd round.
