Below is the list of defensemen who have produced points at the highest rate at 5v5 in the last two years. The cutoff is 1000 minutes.
Brent Burns
Erik Karlsson
Dougie Hamilton
Andrei Markov
Mikhail Sergachev
Victor Hedman
John Klingberg
Roman Josi
...and at 9, Jacob Trouba.
So, this defensemen who supposedly isn't good enough offensively to be a #1 would have been the highest scoring defenseman on 25 different teams in the last two years. Y'all must be watching some f***ing awful defenses.
He is an excellent shutdown defenseman. We know this, because he plays the toughest minutes on the team, sheltering less talented defensemen. Even still, he has had some excellent results in terms of xG, ranking him near the top of all defensemen. Here is where shots are coming from with Trouba on the ice. (hint: at both ends, the results are great relative to his teammates)
They also tell you that Trouba doesn't drive his pairing. Except that it is literally what he has done for the entirety of his career. Always being the one who elevates the pairing, regardless of what shit he has been given to work with. Everybody does better with Trouba than without.
Jacob Trouba is a #1 defenseman, and it requires irrational hatred or ignorance to claim otherwise.
