Dathan is entitled to his opinion. But we are allowed to pass judgement based on his opinion.
Dathan is no longer a major player in American distance running and 10 years from now high school kids will have no idea who he is. This harsh reality is becoming clear to Dathan and he is cashing out. Take a look at Bob Kennedy and recognize that HS kids today have no idea who he is. Kennedy was bigger than Ritz in his prime.
I will always remember Bob Kennedy but history won't. I will alway remember Dathan, but history won't.
The sad part for Dathan is that those that remember will remember him for his attempts to demean those that are becoming more relevant as he becomes less. Your reputation is not something that the NYRR can buy.
