What's naive is thinking 2-0 teams are just going to pull guys up from being inactive to influential roles because it's helpful to your fantasy agenda.
I don't think they're going to make a change because it helps my fantasy teams. I think they
might make a change because they are having real-life production problems. As of tonight's game they rank 27 out of 32 NFL teams in yards per carry. Last year they ranked 3rd in the NFL in the same category. I don't think you need an active imagination or an ownership stake in Michael to buy the idea that they probably aren't thrilled with their rushing output so far this season. It's a completely reasonable opinion based on how much they've struggled.
Now to be fair there are a lot of variables at work here. Maybe the coaches are thrilled with Randle and McFadden, and blame most of their struggles on the OL. Maybe they think those guys are crap, but don't rate Michael any higher now that they've gotten a close look at him. Maybe they know Michael is better and are just waiting for him to get acclimated before they make the switch. No one here has insider knowledge and no one is claiming to be a psychic, but what we know is that they felt insecure enough about their RB spot going into the season that they went out and acquired Michael. Even though the price was dirt cheap, that still shows some intent. Since then the guys they already have had struggled by most objective measures. So to recap...
1. They had enough doubts about their RB group to trade for Michael before the season started.
2. Randle/McFadden/Dunbar have been one of the least efficient units in the entire league.
And you have to be a delusional C-Mike owner to think they
could make a change here?

Just a person with a functional brain. I think you've claimed not to be biased against Michael in the past, but it seems to me that you're totally unwilling to see anything but the negatives. That doesn't reek of objectivity. I know you were a huge DMC fan back in the day and maybe you're still clinging to that feeble thread, but I have a feeling if this was one of your pet players like Duke Johnson or Cordarrelle Patterson then you'd see the silver lining in the exact same situation.
I think anyone who is being realistic here can acknowledge that there are some positives with Michael (new situation, incumbents struggling) and some negatives (dumped by Seattle for an alarmingly low cost). I don't even fault the skeptics (though I'm more of an optimist myself), but what I find comical is the notion that Dallas won't make a change just because they happen to be 2-0 despite running the ball poorly. Anything can happen here IMO. I wouldn't be surprised if Michael leads the team in carries next weekend and I wouldn't be surprised if he's inactive either. We really have no clue what they're thinking inside the building out there in Jerry World.
