The thing about Tim is that he's one of three Kenyans all under the same coach who are dominating the 1500m. If either him or the Manangoi brothers go down, then probably the other two will as well.
Can you imagine what the 1500m would look like without Tim or the Manangois?
I might be wrong but the potato man and the Manangois aren't going to fail anytime soon. You see Kenya isn't really serious about cracking down on doping, my gosh their economy would collapse. The government needs the foreign exchange and the jobs. Kiprop was a sacrificial lamb to make out they were credible, the suspicious bribes might be a set up where he was tested, he hits up the next day and boom they turn up a couple of days later to catch him glowing. Notice none of the stars are being caught locally (though I could be wrong here), was Jepchumba an in competition fail? Bett simply refused, Jebet, didn't WADA catch her? The rest weren't that big. Any how anti-doping Kenya is sending their blood samples to Bloemfontein, which isn't even accredited. Then there's runners like Kwemoi with a 53 Hct if he was a TdF cyclist back in the mid 90s he would've been banned. Do you really think that a population can pump out that many new sub 2:08 marathoners each year legitimately, even with the help of altitude?
