Shamrock's a good fighter don't get me wrong, and there is a small comparison in his up and down fight record. But i'd have to disagree with his fighting itself. Of course boxing and MMA are WAY different but there is still things that resemble themselves. Yes Tyson went out and threw everything he got untill he became old and washed up, you'll see he gives up and makes excuses. Shamrock makes excuses about the same, but does not give up. The first tito fight he got his butt kicked and was still wanting more. Shamrock's got more heart then 10 tysons.
What is it that is going to be on your mind when you're on your death bed? Will it be the tedious years of 9 to 5, or the memory of some great acheivement. Maybe a moment you stood in glory to the applause of millions.
