I understand your allegiance to the Bears, but are you a fan of football or just the Bears? If you truly are a fan of football, and if you took the time to discover what all Jim Brown did through out his short career, I believe your opinion on Brown would differ greatly. This goes the same for any fan of Barry Sanders or Emmitt Smith.... Jim Brown retired early to pursue a Hollywood career. He could have played another 5 years, averaged another 1200 yards per year easily... and have a career rushing total of 20k+ yards. Remember everyone, the question is of alltime... not of your lifetime.... All time.... and I believe when all is said and done... Ladanian may end up more impressive than Payton.
