What happened: Florida Panthers general manager indicated the club is 'not done' after acquiring Brady Tkachuk, suggesting additional roster moves could follow. Tkachuk was officially introduced this week and is set to join his brother, Matthew, in South Florida.

Why it matters: The comment raises the stakes for a Panthers team that has already made a significant addition up front and now appears positioned to keep building. Pairing the Tkachuk brothers gives Florida a high-end, physical forward duo, and a front office openly signaling more activity points to a club intent on staying in contention.

What to watch: Watch for the Panthers' next move and whether the GM's 'not done' framing translates into another trade or signing. Tkachuk's fit alongside his brother Matthew will be a storyline heading into the season.
