What are you selling? I don't understand your post. In May 1969 the city of Baltimore announced it would seek a “substantial” increase in Memorial Stadium rental fees from Carol Rosenbloom and the Colts. Rosenbloom had already called Memorial Stadium “antiquated” and had threatened to move all Colts home games out of the stadium unless improvements were made.[5] Rosenbloom even considered using $12–20 million of his own money to help fund the building of a new football-only stadium on land in adjoining Baltimore County.[6] By November 1971, Rosenbloom announced that the Colts would not return to Memorial Stadium when their lease ran out following the 1972 season and that he was not interested in negotiating with the city anymore.[7] He wanted out of Baltimore for several reasons — team revenue, problems with Baltimore Orioles ownership relating to Memorial Stadium and food sales/parking fees, a running feud with the Baltimore press, and his new wife's desire to move to the West Coast.[7][8] Will Keland, a real estate investor, was originally slated to buy the Colts from Rosenbloom. However, Keland could not generate the funds necessary to purchase the team. His golfing buddy, Robert Irsay, who originally was slated to own only 1 percent of the team, did have the money available and he moved in to make the purchase. On July 13, 1972, Irsay became the owner of the Colts. Under the terms of the arrangement, Irsay bought the Los Angeles Rams for $19 million, then traded them to Rosenbloom for the Colts and $3 million in cash. The players for each team remained in their respective cities.

In 1971, Baltimore mayor William Donald Schaefer and Maryland governor Marvin Mandel created a stadium committee to examine the city's stadium needs. Their report was a blow to Memorial Stadium. Some of the problems mentioned: 10,000 stadium's seats had views that were "less than desirable"; 20,000 seats were out-dated bench seats that had no back support; 7,000 so called seats were actually poorly constructed temporary bleachers that were installed for football games only. Also, there was inadequate office space for the front offices of either the Orioles or Colts by themselves, much less for both teams combined. Both teams had to share locker rooms. The upper deck of Memorial Stadium did not circle the field, ending instead at the 50-yard line, meaning that thousands of potential seats (and added revenue) were missing. Any expansion plans for the stadium had usually mentioned less attractive (and less expensive) end-zone seats, not upper deck seating. Lastly, the amount of bathroom facilities in Memorial Stadium was deemed inadequate.[7]

Maryland's planners came up with an ambitious project. Nicknamed the Baltodome,[9] the original plan was to create a facility near the city's Inner Harbor known as Camden Yards. The new stadium would host 70,000 fans for football games, 55,000 for baseball and 20,000 as an arena for hockey or basketball. For an estimated $78 million, the city would build a facility that would have kept all parties happy; Orioles owner Hoffberger, Colts owner Irsay, the Stadium Complex Authority (whose Chairman Edmond Rovner reiterated in 1972 that "A major consideration in Mr. Irsay's trading of franchises, was the city's firm commitment to proceed with these plans."[10]), Baltimore Mayor Schaefer and the Maryland governor Mandel.[7]
