Ask the other players, the coaches, and the hockey media outside the cities we beat whether or not he helped or hurt the team on their way to the Cup.
First of all, Wilson's not universally well-liked or respected by players, coaches, and hockey media outside of DC. Far from it. Just as much criticism and outright hatred as there is begrudging respect and gung-ho support. And that's being generous. So I don't think that poll would turn out the way you're implying. (I think you're right, but the majority of the people you're saying we should ask are folks that think Tom should go f*** himself.)
Secondly, we were 2-1 without him during the suspension. His line didn't struggle offensively or defensively without him (they were actually a little better off in both categories). Small sample, sure, but also crucial games versus top-shelf competition.
And before you throw another "You're a Wilson hater!" post at me, I'm honestly a huge fan, hope he stays forever, and wish we could clone him. All I'm saying is that this idea people seem to have about Tom Wilson being transformative on our top line just doesn't prove out. He holds his own, adds a couple worthwhile elements, and drafts well off a couple superstars. But there are no statistics that indicate that he's a boon to that line offensively or defensively. He costs them a little offensively and offsets it with his physical prowess and doggedness in both ends.
It's a wash, but one that serves a purpose. I think the team's performance in those games during the suspension probably had a "Let's win it for Tom!" vibe akin to how they played without Backstrom. And there's real value to that camaraderie in a sport whose championship is won largely via that brotherhood and bunker mentality.
But the "he creates space" and "he's worth 5m all day long and more soon" stuff is overstated. He's certainly not a passenger on our top line, but his contributions there aren't all that mind-blowing, either.
