Zetterberg retires a Wings unless he ask for a trade and that's not going to happen, Tatar to Edmonton isn't happening since Edmonton is going to be sellers this year not buyers. Holland said that he wont give away Glendeing unless a 2nd come back Glendening is worth far more then a 6th+7th round pick. Kronwall isn't waiving for Arizona get real Kronwall retires a Wing just like Zetterberg. I'd say a 2018 1st round pick+2019 conditional 3rd round pick for Mike Green the conditions that Tampa makes it to the Stanley Cup finals. Fat chance that Detroit would acquire Jack Johnson and then flip him if we acquire Jack Johnson then we will sign him not trade him.

I’m not saying this will happen, I’m saying this is what is ideal to accelerate the rebuild, and a winger is the missing piece in Edmonton.

That's fine we all want the rebuild to accelerate, Kronwall will go on LTIR before he's dealt though Zetterberg is probably only playing one more season then hangs it up don't see Columbus being a team he would agree to play for so you're looking at the cap recapture then. Tatar would be a solid add in Edmonton but that's more of a draft day trade not a trade deadline deal though. Being brutally honest here that roster is far worse then our current roster now.

The worse the team the better the future though when your rebuilding (for the sake of draft picks).
