This sort of sh$t is so comical it defies belief. If you truly understood the economics of Track and Field in the year 2019 you would understand exactly why this is. The only sane person in this twitter "war" is Luigi D'Onofrio - the meet director, and that is saying something.
I mean we all know how money is evaporating from the sport in general right? Especially meets like Rome that don't really attract big $$$ from sponsors because the 60'000 seat stadium they run it in is at best 1/3 full - not exactly enticing for sponsors right? Just so we are clear the IAAF doesn't fund meets like the Golden Gala at all - it merely associates itself and gives status to a meet like Rome so those sponsors hopefully choose to invest. Therefore we can mute that absolute clown Carl Lewis from this conversation right now.
At the end of the day it's a business - and the business doesn't continue unless it's profitable - just ask the directors of all the great meets that Europe has lost in the last 25 years (Koblenz, Cologne, Helsinki, Athens - I can go on) . When you run business sometimes you need to make certain decisions to support profitability - in this case is Christian Taylor worth $X to be a genuine return on investment. Apparently not, but Christian Taylor needs to understand all of the above before he gets upset about this. In fact he is very lucky to be getting anything - my guess would be that there are athletes getting basically nothing to show up that would be more profitable to Mr D'Onofrio (such as an up and coming Italian athlete who the Italian home crowd actually gives a f%$k about). If you don't like these simple economics don't do the meet - but you might just find yourself working a day job instead of living the bright lights of the European professional athletics circuit if you want to take this attitude. The only money left in this sport goes to the truly big fish and I mean 1-2 guys per marque event max. Christian Taylor despite being a wonderful athlete competes in a mediocre event that doesn't really captivate the imagination of spectators and is not a big fish in that respect.
As for Will Claye I have to truly laugh out loud. 10k alone for just getting on the ground is comical. This legitimately represents an appearance fee that maybe only a handful of the athletes in the meet may hope to attain. My guess is that the athlete budget for the entire meeting (travel, accommodation and appearance) is around 500k euros. Will Claye sitting in business class is not worth 2% of your budget - especially for an 8hr30 flight - get real mate. Noah Lyles? Yes. Will Claye? Dream on kimosabe. I can't even believe Luigi would even contemplate that amount for him.
Track and Field is a hard sport. It's become and even harder business.
