Analysis:
Notable that Bednarek isn't listed. I dont see betting on the field as an option, but that might be a good bet if they are just going to ignore Kenny B.
You have to like Kerley at +1600 and Omanyala at +2300. Kerley seems to be improving at just the right time, has the fastest PR, former world champ. Omanyala is probably close to the right range, but has to be a much better bet than Simbine (has only run 9.94 this year) at +1600 or Jacobs at +2300. Jacobs is actually showing better form than before the 2021 olympics, so maybe I can be talked into Jacobs being a better bet than Omanyala, plus every year Omanyala's season best is run in Kenya, so he's not likely to run a SB in Paris.
I'd like to be able to bet on an athlete making the finals. I think Ashe would be a good bet for that. He is listed 11th most likely to win (12th if you include Bednarek), so I would think there would be a good return on betting him to make the final, which I think he will. He has proven to run rounds well, and there are some question marks for the athletes listed ahead of him.
Nice to see no overwhelming favorite to win. Not sure what the odds were going into the 2021 olympics, but looks like they are giving Lyles a 36% chance of winning? That has to be fairly low historically for a favorite. Odds really point to it coming down to the Jamaican and USA champs, and making Lyles the slight favorite of the two at this point makes sense, but I'd bet the field between the field and Lyles. If they put Kenny B at +2300, I'd wager a ratio of 100 on Thompson, 25 on Kerley, 25 on Kenny B (or Omanyala). Combined, the odds imply a 43% chance the winner is one of those three, while I think it should be greater than 50%. You'd make $50 with a Thompson win, $250 for a Kerley win, $425 for a Kenny B/Omanyala win, or be out $150 if anyone else wins. Or I'd just go with Thompson to not dilute my winnings.
