Let's see, not including Gilmour, Hickey, Rafikov, or AOM; this is our AHL defensive depth right now and/or next year going by useful experience:
Potter (Probably doesn't return next year. He's probably choked about getting a grand total of two NHL games before Schlemko upended him.)
Yonkman (Probably doesn't return next year. Was their Captain this year though)
Ramage (RFA... I doubt he has shown enough to warrant qualifying. )
Acolatse (RFA... Righty blast from the point. Has really come on in 2015 with 5 goals, 8 assists, +6 in the last 19 games. Size is average but probably not what Treliving is looking. I wouldn't be shocked to see him qualified but he's also one of the more likely to get the cut)
Cundari (RFA... Tough to say if he gets qualified, I think he can be an NHL bottom pairing guy right now but we're not the right team for him due to his size. He'd instantly be a top pairing Dman on the Oilers for reference.)
Stevenson (AHL Contract, Huska really seems to depend on him. I'm not sure if he gets an NHL-style contract but it wouldn't be surprise if he does)
Morrisson (Has size [Conroy says he's 6'3?], skating, right-handed rocket. Hopefully transitions well enough that he can be brought up to the NHL as his package is exactly what we need out of a #6D right now)
Yevenko
Wotherspoon (Hopefully graduates next year as he'll be a 3rd year pro at the end of his ELC)
Culkin (going into his 2nd year of ELC, injured right now. Looked strong.)
Kulak (going into his 2nd year of ELC, looking strong right now.)
Sieloff (Despite being a 3rd year pro, only going into his 2nd year of ELC as his first year slid. Also missed that first year anyways.)
Kanzig (will enter the 1st year Pro / 1st year of ELC)
Eric Roy (Probably doesn't get signed, unless it's as a LW. Because we totally need more LWs

)
Jason Fram (We have no claim to him, but he was a standout during our prospect camp as 19YO and it wouldn't be a surprise to see him given a contract when his CHL season ends)
