Actually I have. You clearly have no idea how sometimes prospects don't live up to their expectations. There's no reason for us to re-roll a very successful pick.
If you think that potential beats proven, you shouldn't post here. At all.
Cute. Certainly we can attach a level of reasonableness to whether a player will turn out or not, it's hardly a coin toss in the case of a prospect of Werenski's calibre. His intelligence with the puck, his smoothness, his offensive instincts, and the strides he took defensively this past year are all incredibly positive signs. He's not a low IQ player relying on physical tools to beat weak competition, and he's noticeably improving on what was his biggest weakness. The notion that somehow the Jets could demand Seth Jones, a player who displayed a higher ability in CBJ than Trouba has, who has higher offensive potential, who (IMO) is significantly more likely to be a #1 defensman, and who is actually signed, is laughable. Your other statement that somehow CBJ would jump all over this is equally ridiculous, especially since their fans in this thread have already shot that one down. I guess you know more than Columbus fans and what they need? With that arrogance, I can certainly understand why you don't think it's necessary for the rest of us to post, you've got it covered.
I'll also add...if the Jets can keep Trouba at a contract long term they are comfortable with, fantastic, but considering this OP is a Jets fan, I'd say it's based on the unspoken premise something hypothetically can't get done. In that scenario, the Jets should thank their stars if they could get a Werenski level defender back, because most certainly nobody is trading a 1 for 1 LH equivalent of Trouba, except signed. Werenski's potential, handedness, close to NHL readiness, age (fits in with Ehlers, Connor, Laine, Schiefele, etc.), and expansion draft exemption make him about the best return I think the Jets could look for if they needed defense back. Keep laughing, I guess.
