What happened to Chambers?

From looking at the video, can anyone say what happened to my man Dwain in the Euro finals?

His 10.21 in the heats looked totally effortless. He came out in the final and looked like he got a monster start, but then got eaten in the last 20 metres by Mark Lewis-Francis- wtf? That should never happen, this man ran 6.48 and 9.99 already. Am I mistaken, or does it look like he started to push out the back too much by 80m, and by 90m he is just hanging on?

Is this a speed endurance issue? Mechanics? I notice that his hip height at max speed isn’t the highest.

Comments?
