I think this is overblown, but heck that's not surprising in the offseason. It will ultimately be Joe's call on who starts, but I think it is a collaborative decision because they have to be in agreement of who is starting so Ireland knows if there are needs to add to the team. For example, if Philbin is dead set on starting Matt Moore, Ireland has to agree with that and make moves that don't affect that decision. You don't go out and sign Peyton Manning if the head coach is set on Matt Moore, so I think that is ultimately why it is a collaborative decision. It is not Joe saying that Nate Garner will start at LG, but Ireland says "No you are going to start John Jerry."
I am not losing sleep over an unclear comment that can be argued either way and was hard to hear anyways because of the wind. Not a big deal, but those who want to make a big deal will.
