That isn't true. It is rare that you would break a leg playing basketball or any bone at all playing baseball. It happens all the time in gridiron football. I wish I could find the chart where I got this information. The strange thing was, if I remember correctly, that the 2nd worst sport was women's soccer, because so many people tore their ACL.
"It is rare that you would break a leg playing basketball or any bone at all playing baseball."
I read somewhere that a lot of baseball players will just call a cab if they have to walk more than a block or two because their ankles are so shot. Not sure if this is true or not though.
