Any word if the deal is standard?
No this deal isn't standard. Cancelling the Trials with no notice is not standard. The guys at Mt. Sac were surprised by the offer of 2021.
update: when I say no notice I should have said "proper notice" as it's clear USATF had problems with the bid in October 2017, but after that date, a November cancellation date came and passed, and then USATF sent a contract for Mt. Sac to sign to host the Trials in January and then according to Mt. Sac never said anything about cancellation after that
It might be standard to negotiate something like this, "we don't think you're going to be ready for 2020, how about we cancel the Trials and give you 2021 instead."
Cancelling 2020 with no notice and then unilaterally awarding 2021 is not standard operating procedure.
I deleted a post saying "It was clear" a bribe had been taken. The more specific an allegation is the more I feel it should be backed up.
My assumption is the plan is to award the 2020 Olympic Trails to Eugene.
If you're building the new Eugene stadium and it's going to be ready by 2020, you'd rather have the Trials in 2020 and the Worlds in 2021 than the USATF champs in 2021 and the Worlds in 2021. If Eugene isn't ready by 2020, then this will turn into a really bad decision because Mt. Sac is on schedule according to their people.
