No one said stupid...it's natural. You have a vest interest in the avs guys. This is what a fan does. I'm guilty of this too... sometimes. Right now Jost's stock is high and Trouba's low. That's all I'm saying. 2/3 years from now it may not be this high.
So, at worst a #2 defender. That's a beast defensively or a 2nd line maybe first line forward....the answer should be an easy one.
If you also look at it from the perspective that Trouba will at some point be our best defender by a considerable margin and Jost will never be our best forward. Probably not even the 4th best forward.
I don't think Trouba's stock is low...in fact, I think it's INSANELY high right now for guy that's never put up 30 points in a season yet. He's a good young, top-4 d-man with room to improve but some people are speculating like he's a slam dunk, future franchise d-man. I don't think he becomes that. When you factor in the contract issues, it's hard to gauge where his value is truly at. Would he accept a long-term deal like Seth Jones and Ristolainen? If not, that's a tough one.
As for you 2nd point, that's the worst argument one can make, imo. Since Letang is the Penguins best defender does that mean he has more value that Malkin, the team's 2nd best forward??? It's a bad argument...for obvious reasons.
I'm going off Bendy's prediction.
Which predictions would those be?
Trouba - I ranked him 5th overall in 2012 and compared him to Erik Johnson.
Jost - I ranked him 4th overall in 2016 and compared him to Ryan O'Reilly.
So the question then becomes, would you trade Ryan O'Reilly before he played a single NHL game for 22 year old Erik Johnson even knowing what you know right now?? (not considering ROR's contract issues)
For me the answer is no because we've already got a player like Trouba in EJ. I love EJ and I'd love another guy just like him but not at the expense of what Jost is going to bring to our club. The type of 2-way play that Jost will bring is something that we will need to take the next step, imo.
Now, if you want to bring in Trouba while giving up a guy like Barrie so that Trouba slides into that #3 d-man spot on the right side and maybe takes over for EJ on the top line in 3-4 years, then that's another way to look at things. If you believe that the combination of a top-4 consisting of EJ, Beauchemin, Zadorov and Trouba could handle the offensive load, then I think that's to be considered.
