Properly glued tires don't come off. You can knock them sideways, you can do whatever you want, the tire will not flop off like it did Armstrong's (or Beloki's). Yes, a section can come undone, but not the whole tire. If I can find a picture of the bike after the crash, you can see that the tire is flopping around in the fork. It's painfully clear the tire wasn't glued on properly.

I agree that it's possible the mechanic used just a little bit of glue. I don't see a good reason for it but I can see that it's possible. No one has mentioned this though.

If you roll a tire, you'll dig whatever is close to the ground. Pedal, bar, something's going to hit. The dug pedal could have come from the rolled tire, not the other way around. Regardless, a dug pedal won't result in rolling a well-glued tire.

I did find that Velocenter, specifically former pro racer Todd Gogulski, mentions the possibility of a rolled tire, but they don't show the bike after the crash. No one else has mentioned it that I can find.

I just find it really odd. I figured someone would mention it the following day or something.

Maybe the team doesn't want bad publicity, I don't know. I certainly wouldn't blame the tire or wheel company unless something actually failed, and it doesn't look that way to me.
