I like the move even if Darling doesn't sign. It's worth taking a shot. Canes have a 1st, three 2nds (Car, NYR, PIT), and three 3rd round (NJD, CAR, OTT) picks in this draft. Couple that with the last few years:
2015: 9 draft choices + acquired prospect McKeown
2016: 9 draft choices + acquired prospects Zykov + Saarela
2017: 11 draft choices (7 in rounds 1-3)
There's no way Canes were going to pick all 3 2nd rounds and all 3 third round picks so worth a shot. My understanding it was Ottawa's 3rd round pick which is the latest of the 3. If Darling signs, then great. If he doesn't, we aren't out much.
