M800: Are Dobek and Rotich going to contend this year after last year's medals? Good test with neither doing much yet. Mariano Garcia is the most intriguing after his indoor season, and then you have a bunch of could-be medal contenders in Bol, Rowden, Hoppel, Arop, Murphy and Kinyamal. Huge field, hopefully someone goes with Sowinsky so it's not sit-and-kick. Good to see how Jake Wightman goes as well.
