The premise for NJ seems to be that Nemec starts back with the big club next season and can play in the NHL at a second pair level for say 8-10 years. I doubt they just view him as a non-roster player.10-16 mid 1st + Evans 50% (Needed 3C at almost league minimum) and change the prospect to Tuch for the heavy 4th line player B prospect.
With this offer, you fill 2 holes and have a good 1st to fill the needed scorer rôle and you still have cap space to do so.
This is not bad for a non roster player.
