Muss said nothing wrong and Ms. Webb even acknowledged that fact. That ESPN issued an apology was just covering their butts since anything you say on air is going to tick off somebody. Muss issued HIS apology because he wants to stay employed without making a big deal of things.
As such -- its pretty much gone away already. If Muss had said "Screw you. I didn't do anything wrong" then the story would have blown up and it'd still be on the top of our radar. He has every right to say that -- but why the headache? He loves his job. Which is not to judge beauty contests.
