When has this player ever established himself as an NHL regular? It's not even about 'replacing' him. His play dating back to over a year ago has him slowly losing his grasp on a top six role.
Like it or not, he's in a similar position as Bear was last season. Cap space is getting tighter, younger players are pushing for opportunities and the team is going to be prioritizing a competitive roster over sheltering a struggling young forward.
As it stands I have Yamamoto ahead of our first as the likeliest trade chip to be moved this season.
