I actually thinks that's a pretty bad list. Most of those are big reaches for Pesce in terms of value.
Huberdeau if traded would fetch more than Pesce for sure
Connor is still an RFA and having a great year. He'll be signed to a big time deal
Reinhart, see Connor
Tarasenko, see Huberdeau
ROR, is having an excellent year and STL has no reason to trade him
Schmaltz is the type of player that we would want but only has one more year on his RFA status, he'll be locked up as long as he continues his progression
It would be a player who is young, good, but not amazing and already locked up at a reasonable rate. The team trading him would be able to lose him and not open up a giant hole.
