Yeah man, that Charlie Dobson could really be in the mix. He has 44.38 PB (he ran in same race when Doom did his 44.15). It's interesting that he also has a 6.59 PB for the 60 (the guy has major speed). Dobson is only 24, so has all kinds of upside. Doom is 27 and probably near his peak. I could see Doom breaking 44.0 at the Olympics and getting into the medals. Dobson is like a wild card.
I wonder what is up with Havard Bental Invaldsen (HBI). He had a PB of 44.39 in 2023, but has only managed a 45.37 this year. He is only 21 years old, so any injuries should clear up relatively quickly.
