The funny thing is that none of them ever seem to improve. Think about it. They all show potential early in their careers and progressively get worse as time goes by. You saw it with McNabb, Culpepper, Vick, and you are seeing it with Newton this year. The body breaks down a lot faster with that style of play. Most running backs can’t even last a full year or play at a very high level over a career and they are built for and train for that punishment.

Doug Williams. Improved. Quite successfully.
RG is a huge talent. From what I see, he’s a ‘character guy’ too.

Funny though - the article makes the same point Rush was vilified for.

You can't put McNabb in that category. He was an elite QB for a lot of years and was more of a pocket-passer. He did run, but he picked his spots for maximum effectiveness.
