Since Mangess’ firing/leaving (depends on who you believe) the NOP and employment under Salazar there has been significant animosity between the two. Much stemming from Magness’ claim of WADA rules violations at NOP and ethics charges against Salazar. Salazar retorted with his side of the story and reasons for letting Mangess go.
Additionally both are very different personalities with Magness being media-centric/savvy and Salazar being media-adverse.
I find it helpful in situations like this to take personality and likableness out of the equation and look instead how the two coaches handle similar situations.
The past 2 Boston Marathons serve as good opportunity to do just that.
Boston Marathon 2018 - just days before the event a Salazar coached Jordan Hasan had an MRI done on a sore foot. When result showed a stress reaction near the point of fracture, Salazar advises Hasay to not run the race, take time to heal-up and look at the longer term of career. Hasay followed that advice and went on to race Boston the following year finishing 3rd overall.
Boston Marathon 2019 - just days before the race a Mangess coached Sarah Crouch had an MRI done on a sore thigh bone (femur) which revealed a stress reaction close to fracture. Magness consulted with Crouch and ultimately they decided to race the marathon. Sarah’s femur fractured during the race and she ran the second half on a broken femur 18 minutes slower than her goal time. Now saddled with having to heal a femur fracture (which have been known to take 4-6 months to heal) before a Olympic Trials on 10 months.
Very similar situations. One coach advised against racing, one supported (100%) racing. One looked out for the long term career of the runner, one emphasized possible immediate benefits.
It’s strikes me as odd that one who constantly attack the other with claims of bad ethics/morals is the one who guided his runner into racing with an injury and focus on immediate gains and the other is the one he is attacking but is the one who preached caution and long term thinking.
I found this very telling.
