Just like with the FO, there appears to be no accountability as far as the coaching goes. Philbin has failed developing numerous linemen, including CWilliams, McGovern, and yes Biadasz ...who has regressed to the point Dallas has tried to replace him but also have failed. I feel that this position flex is a bunch of crap....draft or get your OT, OG, C and develop them as such. All you do with this flex thing is confuse and delay development. Especially when they are only rookies. The only great linemen are great because of their talent...i.e. Martin, TSmith, Fredbeard, and even Collins....coaching made little difference to them.
