It's rough having teams try to poach your good players for a collection of lesser pieces with no consideration for your team's situation and needs. I feel for you Buffalo fans.
Like I get why people would try this with Cozens. He's underperforming, his contract is pretty risky. Maybe you can buy low and convince the Sabres to cut their losses. Thompson though? They're not going to accept the trade unless it's crazy.
Habs fans, start your proposals with Suzuki and a top 3 protected first, then add another asset you consider untouchable, then maybe, just maybe, you'll get the attention of Sabres fans.
