Costa's ceiling--his very peak--is probably slightly better than adequate for an NFL starter for the next few years. I'll take that any day for a street free agent.
Honestly, I just appreciate how hard these guys have to work to even make a roster. That he was able to start for Gurode in 2011 was very impressive in my book, and you'd have to have monstrously unreal expectations for the player to not expect him to need time to develop during that first year. And he did improve that season. And he looked to me to have improved again in 2012. Not just in the BAL game, either.
Now, Frederick's probably going to take his job. Even if he's not better off the bat, the safe bet is he'll be better long term. That's good for the Cowboys, and I have no problem with it at all. I'd like it if Costa plays so well that the team considers moving Fred to RG, honestly, because that would also be a good thing. Either way, though, our lack of depth at C absolutely handicapped us last year. I completely understand why Callahan didn't want to risk going through that again.
I don't think either of them are likely to play for us at Gurode's level at any point. I'd love it if one of them did, but that's a high bar. Talk about your underrated Cowboys players. Gurode was a very, very good Center for a long time for us.
