Antonio Brown’s New Live-In Chef
You missed the Cleveland Browns of the 1950s (1950 inclusive) who won 3 championships. I would argue they were the more dominant team of that decade than the Lions; Browns won 3 championships while appearing in 7 title games while the Lions won 3 championships appearing in 4 title games. That said, all of the Lions games were against the Browns so they went 3-1 head to head.
I added the Browns to your list
Thank you. Edited my post as well.
