I don't love the idea of completely jettisoning the veterans. I do think you'll see a good mix of veterans and young guys when Berhalter, Vermes, or Marsch gets hired. It's one thing to go completely young in these friendlies without a head coach, it's a whole other thing when you're playing in tournaments and WCQs.
There are guys in the pool like Yedlin, JMo, and Nagbe who have played little to none in the last year who will be reincorporated when a head coach is named.
I'm far more interested to see what happens to MLS players who have been discarded or ignored altogether, guys like; Walker Zimmerman, Christian Ramirez, Tim Melia, Bill Hamid, Dom Dwyer, Cristan Roldan, Ike Opara, etc.
