I think the Trials is more fair than anything else proposed. Top-3 demonstrate fitness on the day & deserve to go. It's clear. Every athlete knows what they have to do to make the team. It doesn't erase the previous 18 months of training/racing. That time is spent getting yourself the kind of results that make you a threat to make the team. The examples given don't really make a case for abolishing the system imo. O’Brien wasn't a marathoner. No heighting at the Olympics would not get you a medal, even if he has great credentials. They wouldn't say let's upgrade you to gold because we know how good you are. Samuelson battled through injury & made the team. But if the injury was bad enough she wouldn't have made the team and wouldn't have raced in LA the way she did. We can't just put Seidel on the team because of her bronze. That was in 2021. Fitness changes. It takes time to recover from injury & get fit again. The reality is that a dozen women have a realistic chance of making the team. Seidel could've been 1st or 7th. There's enough talent that you're not thinking the team is going to be weak because you're not sending her.
Leaving it up to USATF is the most laughable thing to consider. It's not the 1920s? Then why does Nike have a monopoly on USATF & why athletes are restricted to certain gear when they make teams & why can't athletes deck themselves out with sponsor logos on their jerseys? We've seen Athletics Kenya miss time & time again with their selections. Most recently, they left one of their best marathoners off of their provisional list (& then corrected it after public outrage but public outrage can't be the fallback). The reality is AK has much more talent than slots. Yes, they can choose to send Kipchoge & Kiptum but if those guys didn't place top-3 at a Trials event, their team would be plenty strong. You could argue that we never send all of the best athletes to the Olympics because the best marathoning countries still only get to send 3 athletes. But I'm not doing that. The Olympics is about everyone sending their 3 best athletes and letting them mix it up on the day. Again, if Kipchoge doesn't win gold is there a rerun? Do we acknowledge that he's the goat & redistribute the medals.
For a sport without a ton of drama, the Trials gives us some of that excitement. We have a ton or 2:08-2:11 men. Good luck picking your top-3. That's why you let them prove it on the day. Christine Clark proved she could handle the conditions better than everyone else. She won by 2 minutes. & clearly times have changed. She was the only woman under 2:35 in that race. She finished 19th at the Olympics in 2:31. It was a different era. She didn't go to Chicago every year to try to run fast. She ran her local marathon & then raised her game on the national/world stage. In 1996, the US went 10th/31st/DNF. I'm sure she would've been seen as one of the best domestic runners if she was invited to run the best races. How do I know? She beat everyone at the Trials.
