Seems to me DQT took off hard because that is the normal pace to dominate a sprint finish, and normally their sprinter (Jakobsen) has no trouble keeping up. Today he (apparently) just didn't have it. If he had kept digging because he knew he could finish strong, he likely would not have sat up .... (of course this is all speculation .... ) but I figure his team realized he had nothing, and his lead out train just kept going hard to get a team win.
It is quite possible that he told his team mates ahead of time "I am not feeling it today ... i fi I drop out, keep on." Maybe not. But these guys are pros. They have dealt with all sorts of scenarios.
Sure, maybe the whole team just screwed up and maybe they all had their radios off .... or whatever.
Fun race to watch anyway.
