Talitha Diggs is the most interesting name in the bunch because she totally changes the game for Femke Bol in Glasgow, if Diggs makes Glasgow and advances to the final with a good lane.
Diggs is not going to tolerate the European and now Klaver approach of sitting back and allowing Bol to cruise to an uncontested lead in 23.5 range at 200. Last year at NCAA indoors Diggs took the lead against Britton Wilson and maintained it deep into the backstretch. Wilson passed her and ran a fantastic time, the second fastest in history.
That's fine but it doesn't automatically translate into Bol doing the same thing. Everything is more complicated at 400 indoors when you trail on the second lap. Bol lost twice at 2022 world indoors, first when Stephanie McPherson took the 200 lead in the semifinal and again in the final when Miller-Uibo led at 200.
Bol has more early speed now than in 2022. I could see that being a frantic and perhaps bumpy dash to the corner. Alexis Holmes might do the same thing. Once Bol and Holmes had that moment in Budapest it seemed inevitable they would meet again in a high profile setting. That's the way these things work out.
