Wejo, I don't think reporters have to be "cheerleaders" for the sport by any means, but I disagree with the idea that there's a choice between being a "cheerleader" or being Phil Hersh.
There a lot of times when a "difficult" question might tick off an athlete. These are the times when things other than the question itself take on more importance.
If an athlete really bombs in a race (not saying Hall did, I'm just saying, hypothetically) a journalist should ask why, definitely. But there's a huge difference between asking "So, your performance today wasn't what you expected, why do you think that is?" and asking "Wow, how does it feel to come out here and fail in such an important race?"
In Hersh's case, it's pretty clear he's got some problem with what he perceives Hall's attitude toward running and racing to be. I'm not a huge Hall fan myself (too Jesus-y for yours truly) but I can be objective, too. I bet if you had asked Hall a similar question about what it means to make the jump from best American to WMM contender and done so in a less dickish way, there'd be no WEJO DISRESPECTS HALL thread. The source of the question and the openly insulting way it was asked (in response to a throwaway comment at the end of Hall's response to a different question) is what makes a legit question cross into the "dick" realm.
Hall was beaten today by 4 men. Even casual fans know marathon majors are races of attrition, where the lead pack at the halfway mark tends to disintegrate. If Hall had run splits of 64/64 to be way back at the halfway and move way up as other elites dropped out or started dying, that'd be one thing. Instead, Hall was with the pack at halfway before getting dropped with a 4:36 14th mile, as your recap noted. No, it wasn't an awesome race for Hall- but it wasn't some disaster that demanded an immediate explanation, either.
It's not like Hall went into this race going IMMA WIN IMMA WIN. In a race with ~10 elite athletes, you don't bet on an athlete- you bet the field. Maybe the press and the blind are "expecting" Hall to win a WMM, but I think that's a foolish expectation. Hall has a shot to win one, just like pretty much any ~2:06 guy does. However, there are a lot of 2:06 guys out there. I wouldn't "expect" one to win a race over another, certainly not over a guy like a Mosop or a Geb-Gebre or a Wanjiru. Maybe the press would have fewer demands for reasoning if they weren't consistently inventing expectations?
