The first trick, though, would be the price to pay. It would be high. If the Sabres put their captain and best player on the market, they would require bankable assets. The most equitable conversation would begin with Pastrnak or Charlie McAvoy, both of whom the Bruins adore. Pastrnak, 24, is an offensive firestarter whom the Bruins stole in 2014.
McAvoy, 23, is the Bruins’ MVP this year and blue-line alpha dog.
It wouldn’t end there.
“I think you’re looking at McAvoy and Frederic, probably minimum,” said the source. “Minimum.”
An alternative template of young player, prospect and first-round selection would probably not fly. Traditionally, young stars move for similar pieces: Patrik Laine for Pierre-Luc Dubois, Seth Jones for Ryan Johansen, Jonathan Drouin for Mikhail Sergachev. If Buffalo moves Eichel primarily for futures, the franchise would signal yet another rebuild to its fans and sponsors.
Multiple bidders could drive the return higher. Minnesota, which already made one deal with Buffalo (Eric Staal for Marcus Johansson), would pursue another. The Wild, screaming for a No. 1 center, could offer Kirill Kaprizov. The Rangers would also be interested in reuniting Eichel with David Quinn, his former BU coach. New York is loaded with potential, from Alexis Lafreniere to Kaapo Kakko to K’Andre Miller.
Other possibilities include Vancouver, either with Elias Pettersson or Bo Horvat, or Los Angeles, which has future NHLers in Quinton Byfield and Alex Turcotte.
