You're correct in your argument with
@The Great Weal , Robert Thomas, if traded, won't receive the best offer of any forward in to he cap era.
Taylor Hall, who went on to win a Hart, was traded for Adam Larsson. Edmonton wanted more, but that was the best offer available.
Alex DeBrincat, young and one of the best scorers in the league, was traded for a single 7th overall pick, and then traded for forward Dominik Kubalik, defenseman prospect Donovan Sebrango, a conditional first-round pick in and a fourth-round pick.
Phil Kessel was traded for two 1sts (expected to be in the teens) and then later, went on to win a Conn Smythe, traded for Nick Spaling, Scott Harrington, Kasperi Kapanen, a first-round pick and a third round pick.
Pierre-Luc Dubois was traded to Washington for a goalie, Darcy Kuemper.
Patrick Laine was traded for free because the other team took on the cap hit.
Robert Thomas also comes with a long term 8.125 million dollar contract.
A reasonable offer for him is approximately 1st rounder, 3rd rounder, Kirby Dach, Logan Mailloux, assuming zero salary retention. If we go by NHL-wide history, that is likely to be the best offer. This also assumes St Louis actually wants to rebuild, and it depends on where the Habs draft picks ends up.
