It looks like his loose fitting shirt hit the bar first. Of all the T&F athletes who should be wearing tight fitting gear you would think high jumpers would be the ones to do it.
Not so fast, feller. A HJ'er has to stretch and contort. A too-tight shirt would restrict that.
Barshim is the smoothest HJ'er since Dwight Stones. That includes his approach to the bar = very fluid and even.
If they were ever to reduce the number of events in T&F, do you think they would eliminate HJ?
