Is it just me or have we heard this "Virus" excuse from Nop athletes multiple times. Now I am not completely jumping into the PED area but this does seem like a common occurrence (Or excuse) from this group.
I know Rupp has said it before
I know I have heard Hasay say it before.
Pretty sure Cam levins has said it at some point as well.
Even Dathan back when he was with the group
Now me personally being around relatively fast runners I have not seen this happen at all really.
So for me I am left with the conclusions that the NOP athletes train so close to the edge (a lot people mentioned the emaciated look of the athletes) they there immune system just drops off and they get sick.
Or a "Virus" is just a nice term they use because they realize it doesn't require a lot of explanation.(For whatever the real reason is)
