Parayko is bar none the most overrated player on this board. Good upcoming kid, but his 15 points a year don't get you generational talent - unbelievable lol
Always makes me laugh when the ask from Blues is players like Matthews, McDavid, Malkin, Drai, etc... What difference has Parayko made to the Blues? Because one of these things is not like the other... A guy on the second pairing is commanding a #1C? Yeah, not happening. To be honest, I highly doubt the Blues management or ANY management around the NHL values him anywhere near that.
A really good wing + RHD coming back the other way is about as much as you could hope for. Quality RHD are rare enough where the bidding war would only include a few teams if that was part of the ask. If the ask is draft picks or prospects - you've got nearly every NHL team in the fold. Most NHL teams have a really good wing to offer up as well - so either a decent C or good wing + RHD is what you can expect - unless of course he somehow morphs into the generational defensemen folks around here peg him as.
