Bo had seven years and at the very least stabilized the position group. But the oline has had issues in the personnel dept ever since the firing of Callahan. His '08 class was loaded at the Oline position. And Callahan is a straighup Oline wiz. Has anyone watched Dallas last couple years? That's his handywork. That oline some bad dude. I read or heard a little nugget at some point that said (and I'd have to check) that something like 4 or 5 of Callahans Oline recruits that were committed here for the 08 class wound up becoming starters in the NFL. So if one thing really took a hit when Callahan was fired, the oline position definitely did. I think this dynamic really showed in 2009. 2008 we were still riding some vets like Murtha and Slauson.
I know Callahan is a well-respected offensive line coach, but he hasn't been in Dallas since 2014.

And the offensive line was really good then too. That's less than 2 seasons that hes been gone. He spent 3 years there. Did some playcalling one year if I recall. So my point is that he had huge hand-probable the most important hand-in the evaluation, aquisition, and development of their current offensive line. I know there's folks drooling over over Prescott, but if you watch a Dallas game as I have a couple times, that oline is doin some work. Prescott gets time to literally just stand in the pocket for multiple seconds. Elliot, when executed, just has gashing lanes. This is how the 90's Cowboys were built. Oline first. qb 2nd. RB third. And I'm just saying that Callahan deserves monster credit for it.
