You're right there is something a bit off with that ... And here it is, Philbin may have chosen to add Benton and Lazor or he may have been told to add Benton and Lazor. We don't really know for sure, but we do know for sure he chose Sherman and Turner, do we not? We also know he would not have replaced Sherman had the decision been completely his to make, based on his own comments.
We also know that Philbin, Sherman and Turner were part of the decision making team -- including Ireland -- that brought us last years' o-line. I would take from this that, with two new coaches and a new GM, (that I forgot to mention in my original post), it's logical to have faith that fresh blood, having a fresh perspective and knowing the disaster of last years' mistakes, would be hell bent on not going down the same path. Why would they? I would also argue that Lazor, Benton and of course Hickey combined are in a position to at the very least, highly influence Philbins' decision making - which I'm sorry, I simply do not trust at this point in his tenure.
But that's just me.
