It's weird, when I was a kid, I had favorites: Numminen or Steen might have been my all time favorite Jets, but I also loved Olaussen, Housely, Ellett, Essensa and Khabibulin just to name a few.
I've lost that love of player. Sure, I love the Jets, and there are players I like to have on the team more than others, but I think I've had my heart broken too many times from players leaving, either via trade by team or wanting to leave. Selanne really damaged my opinion of the league and love of players (though it wasn't his fault).
Having said all that - I would have to say currently it's Mark Scheifele. Just all round a great player, teammate and citizen.
