Maybe I am wrong in my analysis - but for the next quad, I am betting on Yul Moldauer and Akash Modi being the ones to watch in the U.S. for Tokyo.
I actually think that Whittenburg's best bet is to be an event specialist.
Yes I think this quad will be all about Moldauer and Modi in the AA. Whittenburg will mainly become a specialist type, I also agree. And Mikaluk will gradualy start to drop in relevance from here, maybe not even making the 2020 Olympic team if he is still competing then.
