I'd throw Schmidt on the 3rd pair without blinking twice. Hopefully Orlov comes back strong. That leaves the 2nd pair.
Schmidt OR Orlov will be ok on the 3rd pair. Put both together and its disaster.
They are too young and inexperienced for starters.
Also we won't even have Orlov at 100% until the new year most likely (by the time he gets back up to speed after missing camp and part of the season)
You are asking an awful lot to try and fill that many holes. We will have to deplete our already thin farm system or seriously overpay for overrated UFAs
The other option is your route. Pray to Baby Jesus and watch Green walk in the offseason.
or trade him at the TDL. or watch him blossom under Trotz and return to form.
At the very least it will cover us until Orlov gets back up to speed.
If you want to tank the season fine. Trade Green and play a bunch of young guys who aren't ready.
Fact: We are thin on D. We were last year. Now we may not have Orlov for a while.
Obvious solution? Trade Green and do the "not impossible" and bring in via trade/UFA 3 NHL level Dmen from outside the org.
