It's an interesting thought, as it does address some of our biggest holes, but it's far too much value. I think Dobson is a good target, but only at the right acquisition price and contract value. I'd honestly rather go for Nemec, Clarke, or Morrow this off-season then Dobson, unless he's willing to sign an extremely reasonable deal (Unlikely).
When you break it down, it kinda looks like this - Faulk + 2025 1st + Stancl is already an overpay for the priveledge to sign Dobson for double digit AAV, which he's going to have the leverage to ask for if we're trading that many assets for him. The rest of the trade looks even more lopsided with Dvo and Jiricek for Barzal, who doesn't even play Center that much anymore.
I will admit, these last couple of veiwings of Dvo has worried me a bit - skating is a fickle bitch, and his legs look like toothpicks - but we've generally done well at developing prospects and he's got so much runway left since he was such a young draft pick at the time. I am a bit concerned though.
