Robertson had a few looks in the past but it's not like he played a ton in the NHL either. Cracking the Leafs line up for a player like him isn't going to be that easy, since he's going to be looked to fill a top 6 role. What matters though is where he's at now, at age 21 he still has some time, and he's looking okay for now. He's not irrelevant in Chychrun trade conversations, unless the Yotes are categorically against undersized wingers, otherwise there could be interest. Just because he couldn't crack the Leafs roster in the past (he might this year), doesn't mean he couldn't crack the Yotes roster.
Like I said in my previous post, Arizona's first choice would definitely be Knies and they might stick to asking for him since they probably really want him because of his size and local ties, but if they are okay with undersized wingers they might be open to taking Robertson. He's shown he can dominate in the AHL last year, now it's time for him to prove he can take that next step. He's gotten a bit "thicker" in his own words which might help him a bit.
When talking about the prospects that would be a primary piece in a trade for an asset like chychrun, there can’t be a litany of excuses.
I’m not saying the guy doesn’t have value, and for a good rental at the deadline, Robertson would likely be that kind of asset that could be the good prospect in the standard, “first and a prospect,” deal.
He’s a gamble for sure. Not a lock for the NHL. Has some knocks against him (size, and current failure to perform in the NHL).
In a trade for chychrun, the main prospects can’t be in the, “we can definitely talk ourselves into this guy,” category. They have to be more, “our organization loves this guy and believes in him.” I don’t think Robertson is going to be that guy for any NHL teams.
