If they do pan out, you could always trade from a position of strength to address that weakness?
The way I see it:
We add Stamkos and they all pan out. Trade one of them for a defenseman. Marner or Nylander, if they pan out as Top Line forwards, can fetch a Top 2 dman to play with Reilly.
Last year, 22 defensemen received Norris trophy votes. Of the voting, you have to get to #11 before you find someone who was traded. That's Ryan McDonagh, who was traded before he'd ever signed a pro contract. Here are the other guys on the list who were traded:
Byfuglien
Stralman
Shattenkirk
Leddy
Wideman
Burns
Campbell
So you have two guys who weren't defensemen when they were traded, three guys who weren't established as top pairing defensemen, two guys moved in salary dumps...and Dennis Wideman.
So, no, the idea that you can just choose to trade for a top pairing defenseman whenever you want doesn't really hold water. If one of these guys is available it's likely to be in a situation where a team can't take money back and, even then, may not be a team that wants what you can offer. Even then, you're almost certainly looking at the bottom end of what constitutes a "top pairing" defenseman.
The chances of a player coming up, establishing themselves as a top pairing defenseman and then being deemed expendable by their team is
extremely low. It's certainly not something you can plan around.
