LOL at the headlines for articles saying the exact same thing.. https://racer.com/2019/11/12/mazda-confirms-team-joest-partnership-into-2020/ https://sportscar365.com/imsa/iwsc/joest-mazda-set-to-part-ways-after-sebring/
https://racer.com/2019/11/12/pruett-mazdas-hidden-message/ I didn't know that Multimatic was behind most of the Mazda success and that Joest was the driving point of much of the failure (per the article). If true, no wonder they want away from them so badly.
Both headlines are technically correct. The contract with Joest runs out after Sebring. Both articles are pretty much exactly the same, just different headlines to try to get more clicks. Sadly, it worked.
