No, his job is - first and foremost - to represent Adidas and drive sales of Adidas shoes and apparel. One way to represent the brand well is to run fast (and often), win medals and set records. But there are other ways to represent a brand well: have an active and engaging social media presence with lots of followers (e.g., Quigley), give good / upbeat interviews (e.g., Jones), be provocative (e.g., Lyles, Richardson, Ingebrigtsen), be good looking (e.g., Mu, Valby), be likeable (e.g., Neguse), be relatable (e.g., Hocker), be a role model for certain sub-groups of people (e.g., Hiltz), be clean (e.g., not Houlihan), represent America if you can (e.g., not Duplantis).
Yes, performing well might be a primary driver of market value for many athletes. But the notion that these athletes are JUST paid to run is naive.
These other factors can have a SIGNIFICANT impact on what brands are willing to pay to sponsor an athlete.
People like Rupp, Nico, etc. would probably be worth more if they gave better interviews, were more likeable, and engaged more on social media, etc.
Lyles, Richardson and Ingebrigtsen would not be paid as well if they were just boring, quiet introverts.
Mondo would get paid a lot more if he had decided to represent the USA (a far bigger market than Sweden).
And undoubtedly Shelby would get a great contract in the future if she performed as well as she did in the past, but was clean (!) Whatever new contract she may or may not get will certainly be nothing compared to what it would've been without a 4 year doping ban served - irrespective of how well she runs going forward.
So stop with this "his job is to run fast" BS.
