Not much for the Jets. Top four spots are pretty locked up - Byfuglien, Trouba, Myers, Enstrom.
Then you have Mark Stuart, Brian Strait, Paul Postma, Ben Chiarot and I guess Julian Melchiori (all waiver eligible), plus Josh Morrissey (waiver exempt).
Can't really see the Jets waiving Stuart or Strait, Morrissey may make the team but is more likely to be the first injury call-up. So the top 7 is rounded out by Stuart, Strait, Chiarot. Postma may be a healthy scratch, or may be waived. Melchiori almost certain to go to the AHL and thus be waived.
Only other D prospects under contract are Nelson Nogier and Jan Kostalek, neither of which has any realistic shot at making the team out of training camp (and are waiver exempt anyways).
So:
Melchiori
maybe Postma
