I think the weight rumors started with his plantar fasciitis in the off season. Weight is a big contributor to that. I know someone will say skinny people get it too, but weight is usually the issue.
i wouldn't make the argument that skinny people get it too. However, i would make the argument that people who train hard are very susceptible to it.
i do, and i have had it since my mid 20's... i still train hard, and it sucks!!
The only time it doesn't hurt... is when i am running!! go figure.
