Qwiss Yeah, completely agree. Lyles seems quite extravagant and aggressive, but I hear him speak and think he comes across well and, ultimately, he's right - athletics needs people with main character energy. I loved his entrance. As you say, though, it's one thing to talk the talk, you gotta be able to walk the walk. And he definitely did that last night.
In related news, I've just seen that Molly Caudery learned no lessons from getting knocked out of the Diamond League meet in London early last week and has failed to qualify for the Pole Vault final. I'm looking forward to watching Keely Hodgkinson in the 800 final tonight - I'm getting Jess Ennis 2012 vibes about her, hopefully I'm not reading the tea leaves wrong!
