The real reason Art Modell moved to Baltimore was to avoid bankruptcy on the his team. There was a lease on his team too with a year left over, which is why he left the name, colors and history back in Cleveland for the new team, so he could settle the relocation out of court and get out of it. The first year, he was so broke he couldn't afford a practice squad for the Ravens.
There were rumors later that he sold PSLs at a bulk discount to brokers to raise funds, that why the NFL stepped in and had him either sell or get a partner which is where Steve Bisciotti comes in. Bisciotti had offers to buy the Vikings and the Florida Marlins, but chose the Ravens possibly because he lived in nearby Anne Arundel County. He made his wealth through Aerotek, and when he took over majority ownership, he kept Modell as a consultant until he passed away. Mike Preston of the Sun, said "Art was a mom and pop, type of owner" Steve is more corporate.
