seemed like he shutdown at 150-160 and coasted in. Was hard to count the strides cause the video kept on skipping back.

One of the easiest sub-20s I’ve ever seen, perhaps the easiest. I can only think of Shawn Crawford running 19.95 in Athens quarter-final. Tyson’s 20.00 into -1.7 a month ago was easy, not a sub 20 though 
Wow! That was one easy looking 200 by Bolt!
1.7m/s wind in this race. Definitely the effortless 200 ever that wuz sub 20.
I think Mike Marsh’s 1992 Barcelona semi-19.73 into a 0.2-would also be among the easiest ever. Not as completely shutdown/effortless as Bolt’s though.
easiest 200 ive seen 
It’s official man. Bolt is breaking that 19.3 easy.
Hell, he’s gonna go for 9.6 for the 100 also.
