I'll say this, Outside of McDavid who is untouchable and probably Draisaitl who is still pretty unproven, Hall is the only guy who probably could get you close to a legit #1 d man.
Eberle wouldn't. Yak wouldn't. RNH wouldn't. Hall is the guy.
But teams don't trade legit #1 d men. People can talk about the RyJo for Jones trade all they want but Jones played very sheltered minutes in Nashville, he wasn't on the top pairing or even the 2nd pairing.. He's not a legit #1 d man. Does he have potential to be one? Sure but he isn't right now. He actually might be over rated a little bit.
But if you want a legit # 1 d man or a guy close to that, a guy like Jones who could become one, Hall is your best bet to trade.
