With an eye on this being a full-on rebrand, I think Cleveland Flame is a great choice. Here’s my idea for a video announcing the launch of the new branding:
Tom Hamilton: Our City of Cleveland has always burned. More than a century ago we were the city of light - the first in the country to deploy electric streetlights. We fueled the nation as the headquarters of Standard Oil, the epicenter of the world petroleum industry. We ignited the birth of modern physics at Case Western University and earned America’s first Nobel Prize.
