The majority of Browns fans do not like Lerner, since he has been a failure since he took the team after his father died.
That being said, the new guy is a minority owner in the Pittsburgh Steelers, so there is some natural fan resistance to that as the Browns and Steelers are basically the Sty vs Villa of the NFL. As a Browns fan myself, I would say that losing a billionaire owner is never a good idea, yet I don't think Randy understood American Football at all. It's too bad the local guy couldn't make us a real contender.
BTW, in case you are curious, the Browns are worth about $800 million, and I'm sure that Lerner will also make a profit. So it's understandable if Lerner was interested in selling it all off. It's too bad he couldn't do what his father wanted him to do, but I think it's time to move on.
