Should the Pens actually get the first overall pick, I'm sure they'd receive plenty of interesting offers. Right now I'd only consider offers from LA, Ottawa, and Detroit given who the top 5 are in the draft (and this is because I have only looked at those teams' prospect pools, and not teams such as Buffalo).
For LA, I'd trade the first overall for the second if they were to include one of their top expansion draft exempt prospects and perhaps another pick (Turcotte or Kupari perhaps? Vilardi is interesting too but has had injury/back issues). I'd then draft Byfield.
For Ottawa, I'd trade the first for the third and fifth overall. I think I'd also try to get the 21st overall.
Like mentioned above, I think I'd also try to get them to take JJ. Assuming LA drafts Byfield, I'd then take Stutzle. I'm unsure of who Detroit would take at 4, but then I'd take Drysdale, Raymond, or Rossi at 5 in that order of preference. If the Sens wouldn't give up the 21st as well, I'd like to acquire Brannstrom. Actually, I'd prefer a higher end prospect as opposed to the 21st.
For Detroit, I'd want their fourth overall, their 2021 1st, Zadina, and something else of note. Veleno is intriguing.
I can tell I'm aiming big, but I have no clue how much other teams would value Lafreniere.
