I'm not against moving our 1st, haven't been against that since 2017, However I'm not sure it needs to happen.
Will Tanev cost a 1st? I'm not convinced he does especially given what Zadorov cost Vancouver, Tanev will likely cost more but I'm not sure his price is so much more that It's a 1st round pick compared to a 3rd and 5th.
If Arizona falls out, I'd be targeting Matt Dumba too, and I don't think he'd cost a 1st but I do think he'd be a significant addition.
At the same time if Carolina goalie issues cause them to fall out and Bret Pesce becomes available you put that 1st round pick on the table because Brett Pesce would be the PERFECT partner for Rielly.
Same thing with Hanafin especially if he comes with an extension ready to be signed.
EVERY single pick and EVERY single prospect should be available but, the type of D we need may not cost a 1st.
