Jerome Bettis vs. Barry Sanders?

I'm a Steelers fan and I am NOT as bias AS YOU. I'd take Barry Sanders if I want a pure speed running back. I'd take Bettis if I want a RB that I was sure would get me the yards when I needed it. You can call Sanders a quitter if you want. However your bias is so blinding it's pathetic. Where have the Lions been SINCE Sanders if he was holding them back? Where are the Steelers WITHOUT Bettis?
