Maybe Seto will focus on the IM's where he could actually win more than bronze. There are a bunch of guys besides Burdisso who could swim in that 1:52 high or 1:53 low range, for example Kenderesi and Horomura. I think bronze will be between Burdisso and Kenderesi.
Would make absolutely no sense for Urlando to switch, he can easily make the US team and the US is a much bigger market + he clearly sees himself as american. Italy is in a good spot, it was already pointless to add Condorelli to the team. Must suck for italian talents that someone like Condorelli was chosen ahead of them.
You would think that Pellegrini finally has to slow down, but she seems to be able to stay at that 1:54 level a bit longer. I don't think she can go faster than that, which might be what you'll need to medal in 2020 against Ruck, Titmus, Ledecky, McKeon, Haughey.
