I'll just re-post what I said before. Leg cramps can be completely debilitating. It's a lot like back spasms. If you've never had them bad before, you just don't understand what it's actually like.
"There's no doubt that hockey players play through injury (the intelligence of that is for another discussion), but in my opinion, talking shit about Lebron is extremely tacky. It makes they look immature and jealous.
I believe that some of you have never fully experience a full-on serious hamstring cramp. After a day of basketball when I was younger, my right hamstring cramped up so hard it actually tore fibers. I ended up with the worst looking bruise of my life that went from my right hip all the way down to below my knee. I guarantee that no athlete, in any sport, would just play through something like that."
