I don't know if there's a generational correllation, but the extreme few who don't see anything wrong with what Lassiter did appear to be either former teammates or youngsters.(I may be wrong because no one can tell)
At one time giving an honest effort was a principal that had value. Competing for your country was an honor under any circumstances. There was a difference between running for Nike and running for U.S.A., Great Britain, Kenya, etc. I'm sure USATF had a goal to win this meet and allotted plane tickets, per diems, and hotel rooms for athletes they felt would compete their best to place as high for their country as possible. The World Cup, yes, is not the biggest goal for a world class athlete but believe me winning the team title was probably made clear as an objective in every nation's team meetings before this meet started.
Whether any or every athlete felt any obligation to anyone but themselves is probably debatable. To these selfish individuals perhaps the team concept is outdated. But at one time when you were chosen by someone else, especially your country (and I'm defining USATF as a governing body representing the U.S.)to do a job, you did it and you did it with pride. Or at the very least you sure as hell made it look like you were trying and didn't blatantly make a mockery of the importance of competing hard for your team.
If Lassiter was so tired and lacked confidence, why not give up his spot? Or at least I would think his best tactic would be to slow the pace up and hope he could outkick as many runners as possible. Going out in 1:50 is clearly not a sound competitive tactic for someone who believes their fitness is not up to par. Fuck him and f*** anyone who supports his behaviour. I don't think any discipline will affect him if he didn't figure out he was wrong to begin with.
