I don’t know why the focus of his commentary is around predicting outcomes.

Peirsol was a 1:39 SCY backstroker. I think that was during his Freshman year so it’s likely he would have gotten faster if he kept swimming collegiately, but Kos is a 1:34 backstroker.

SCY and LCM are very different and Kos still has over 1 second to go before he challenges 1:51.

One interesting thing is that even though Peirsol’s record was from the super suit ear, he did not use the extreme suits and he used the style that was hips to ankles, not the full body style.

Try but have to imagine the X-glide leggings alleviated a lot of the work to keep your legs from sinking. Peirsol also didnt’ have utilize underwaters much, Lochte was the first guy to really do it in LCM backstroke

I remember that race – Lochte was actually winning through 130m or so. Lochte was wearing a full body, Peirsol was just in legs

What a huge difference in Rowdy’s commentary – more observant, excited where appropriate but not screaming and drooling. I watched some London 2012 footage recently and thought he sounded fine on it as well.

Watched the video provided by Eric Angle below and it looked like all of the Top 3 wore the hip to ankle suits (Peirsol, Irie, Lochte).

I agree that there’s still a decent gap (1.27 seconds) between Peirsol’s WR and Kos’ PR. A 1:52 this summer would obviously be a good step. That said, I do think he’s capable of breaking it some day.

Will be interesting to see after the meet concludes what a Hubert/Hubert/Nate/Hubert 400 medley relay would have looked like for Texas.
