By early 1941, Rooney was beginning to regret his decision to sell the team he had founded. When he saw that Thompson had not yet established a local office for his team, as he had announced he would do by March 1, Rooney made an offer. He and Bell would trade territories with Thompson. This would put Thompson in Philadelphia, which was much closer to his New York base. It would also ensure that Rooney's team would stay in his hometown. On April 3, 1941, Thompson accepted the deal and Rooney and Bell's Eagles went to Pittsburgh, where they became the Steelers, while Thompson's Iron Men moved to Philadelphia, where they took on the Eagles moniker. This was described at the time as "one of the most unusual swaps in sports history". In fact, though the Pittsburgh team played as the Steelers, they operated under the name the "Philadelphia Eagles Football Club, Inc." for the next several years.
