The 49ers don't really have much of anything in regards to history with the Browns. I found full games, but nothing I could place into the article for out viewing pleasure. As I looked around for something relevant, I stumbled on this interview with Carmen Policy.
This may be stretching it, but along with being the 49ers team president, Policy was involved with the Cleveland Browns, serving as president and a minority owner. He wound up stepping down in 2004. This video is interesting because this is talking about the infamous Proposition G along with the internal family battle between the Debartolos and the Yorks.
