I don't believe most here wouldn't feel good about it. It would he said other teams cheat (all teams cheat) and because the Big Ten is out to get us it simply leveled the plating field. Fans always have an excuse and justification. Notice Michigan turned it into "us vs the world"...did you see Michigan fans less excited about beating Ohio State?We agree on one thing, which is that neither polls nor popular opinion are indicative of reality. Right is right and wrong is wrong, regardless. But I mentioned it because you asked me what fans think.
If you're asking specifically what Astros fans think (which also doesn't impact reality), I don't have any evidence because I don't know any of their fans. But of course many of their fans feel badly about it because that's the only way to feel. All you have to do is imagine your own team "winning" that way. If you couldn't feel good about it with your own team, then why would Astros fans be different?
The reality is we all remember what happens on the field. A title being vacated doesn't change memories or the experience. Michigan, like the Astros, focused on winning. If they win, like the Astros, no decision deletes the memory. Just like when the NCAA vacated our wins...before they were restored I still remembered the games as they existed regardless of the ruling. So will Michigan. So do the Astros and their fans.
