Factoring in the additions from free agency and the draft and what we have seen so far from OTAs (yes, I know some people consider them glorified underwear Olympics), what is the potential Achilles Heel for this team right now? For me, it would be the center position. No one on the team with starter experience at the center position. A big question mark at center right now with Biadasz. Tyron says Biadasz is doing well for a 2nd year player. He's only played a game or two last year but looked decent. Pulled a hamstring pregame and didn't see any time after that. A big unknown right now for backup center. Have the Cowboys penciled in Biadasz at the center position or will they have some real competition from McGovern, Farniok, and UFA from Houston Braylon Jones? I wonder if we might see Steele get a chance at center, or maybe Knight. Center is the one position I would be most worried about at this stage. Injuries and question marks could be most problematic here. I guess Looney might be the backup plan if all else goes south. But, I imagine Looney may find some suitors if other teams get hit with injuries at center. Safety might be a bigger worry for some but I think the center position is much more important than safety.
