Based on London (10.99 for 2nd, beating Block) and Berlin (10.86w for 2nd, beating Sturrup), you'd have to think that Chryste Gaines (hurt at Nationals, only 5th) is quickly running her way onto the team. Given her experience with the stick (Oly gold and bronze, three World Champs golds, World Cup gold, Pan-Am gold) they should already have a baton with her name engraved on it.
I don't necessarily think that you need a good 200m runner on 1st as much. Yes, it is a bend, but it should more so be your best starter and whoever gets out of the whole the best. That is why Angela Williams is such a good first leg yet isn't that hot of a 200m runner. I like Kelli best at anchor. Although I definitely think Devers still has it, she did not do a great job holding on at last year's world cup.
Sorry, Thanos. I have to disagree emphatically. Changing the order from heats to final in the 4x100 is just plain stupid, even though we've done it any number of times. We can pretty well count on getting away with this in the 4x400 but not the short relay.
