There's evidence to support all the things I suggested are likely true: he hasn't considered weaponizing cap space (I recall him saying as much -- that they weren't interested in doing it); he didn't entertain trade proposals for Edler until after beginning negotiations on a new contract (so that when he approached Edler about a trade to Calgary, shortly before the deadline, Edler had little incentive to consider it); the Canucks don't invest much, relative to other teams, in analytics (as your post seems to indirectly acknowledge). So, there's evidence to support my claims of fact, and, as I said, if you genuinely doubt it, I'm willing to do the work to find sources.
There's nothing in my statements about what I think the Canucks "should" be doing that require evidence. Those statements don't purport to be anything other than mere opinion, of the kind most of us enjoy sharing. (For example, some may think analytics aren't that useful. That's fine. If they say that it's obviously the case that analytics aren't useful, that requires evidence to make sense.)
In short, there's nothing ironic in the post you were responding to.
