The argument about Jones has merit,however, I think he's legit. He has raw atheltic ability coupled with a frame that most NHL players would love having. Giving him an overall package that has starter written all over it, he just needs to put it all together (Which I think he's really starting to do).
Not to mention being invited to the Junior Development camp and having two strong showings in the Red/White games isn't doing anything negative to his stock. Look for him to backup Jake Allen and possibly challenging for the starting spot (That's my opinion anyways).
We'll see him compete with Pogge if Pogge is indeed Anaheim bound.
Cousineau is not signed at the moment and has another year of junior eligibility. He's been extremely hot and cold in his junior career and at this point in the game, he should be aiming for a contract offer before he ever gets the chance to compete with anyone for a roster spot anywhere.
