First of all, a player has to know what is banned and what is not banned.

Football is not a game for the weak of heart, because every day you've got a hundred reasons to take all those pads off and say, 'F-k it.'

You can take a substance that works in your system, but then you take this over here that's not banned, and this over here that's not banned, but if you mix them together, you've got a banned substance in your system.

I don't live that life anymore, it's as simple as that.

I played one game, and one game played me.

Hopefully the new breed of kids won't have to go through that hard lesson - my kids, my grandkids, my fans' kids, hopefully they won't have to go through it.

If I'm going to break them, I'm going to break them both.
