Out of all the players you mentioned, I think Cholo has the least probability of success. He doesn't read plays fast enough for the NHL.
I'd rather they sign a LHD, let Lindstrom, Bowey, and Cholo fight for the last spot. Plus Nemeth will more than likely be traded at TDL. If he plays as well as last season, I see a 2nd coming back.
Yeah, while I know he is I haven't really seen why Cholo is in contention for a spot out of camp. Outside of that initial stretch he has been flat out bad, and I don't think he has looked great in GR. Put the kid in GR, give him 20+ minutes a night, and see if he can get his game going for at least half a season before calling him up.
To start the year, I wouldn't be against running something like:
Dekeyser-Hronek
Nemeth-Gudas
Andy Greene-Lindstrom/Bowey
Lindstrom/Bowey
Have to think a lot of this depends on what happens with the AHL, too.
