We already have one of those guys in Jacob Trouba. If your only goal is to go for a "big guy with experience" you're not going to target the right guy.
Go for a guy who is a good hockey player first, size and experience comes after that.
Also, the whole "Cup winning experience" is overrated. I'd take pre-2018 Nicklas Bäckström over a f*** ton of players who won cups for instance. Blais won a cup, who cares? Goodrow won 2. Good for him. That's not what makes him a good fit.
Adam McQuaid didn't bring us a cup. Neither did Victor Stålberg or Jarret Stoll.
