I haven't been able to watch the race yet, but also wonder why Hoste did not just stop working very very early on after attacking and Boonen followed him. Hoste could have stopped working, and increased the chances of Hincapie getting up to him (with the rest of the small group). At least then Hincapie and Hoste would be together (although Boonen would be with Bettini and two other teammates).
