One of the clubs to check in was the New York Rangers. However, Buffalo doesn't want to move its top player, McKenzie adds.
Eichel's agent, Peter Fish, said his client wants to win and is preparing for another season with the Sabres, who drafted the three-time All-Star second overall in 2015.
"I hear that (trade talk) a lot," Fish said. "Jack wants to win, he's frustrated (not winning) but, no, he doesn't want out. Jack is preparing to head to Buffalo at some point here and prepare for the season, whenever that may be. That's all he controls."
Eichel was enjoying a dominant campaign before the pause, putting up 78 points in 68 games while averaging a career-high 22 minutes per night. Despite his brilliance, the Sabres finished outside the expanded playoff bracket in the Eastern Conference, extending a postseason drought that dates back to 2011.
In May, Eichel voiced his displeasure about missing the playoffs again, saying he's fed up with perennially losing, and it's been a "tough past five years."
The Sabres fired former general manager Jason Botterill this offseason and replaced him with Adams - Eichel's third front-office boss since being drafted.
The 23-year-old's current contract runs until 2026 at an annual cap hit of $10 million.
