Les Bowen has received confirmation from Todd Herremans that the LG has been moved to right tackle. This is a move that has been speculated about ever since it became apparent that the Eagles would not likely have either Ryan Harris or Winston Justice to start the season. Obviously they did not feel confident in King Dunlap enough to start him at RT while either Justice or Harris heal.
There's two ways of looking at this. For one, the Eagles are deploying their best assets where they are needed most. Outside of Jason Peters, Todd Herremans is the teams best offensive lineman and they need someone to protect Michael VIck's blindside. So, from that perspective it makes sense to make the move. Plus, they've got a very capable left guard in Evan Mathis (who has confirmed that he will start at LG) to plug in to replace Herremans. In fact, if Herremans plays well there, don't be surprised if this move isn't permanent and the Eagles cut ties with Justice and/or Harris.
There is a more critical way of seeing it however. Herremans is a good offensive lineman, but he's made his name playing left guard. He was a tackle in college and has played some tackle in the pros, but this is a big position move for him. He goes from playing inside on the left to outside on the right. I don't think we can just assume he'll carry on a high level of play at his new position. On the same token, we can't necessarily assume he won't either. Until Herremans proves that he can play RT at a high level, Michael Vick's blindside remains a question mark.
That said, you certainly have to feel a little better about it with the Toddfather over there as opposed to King Dunlap or Reggie Well.
