Some critics believed building the stadium would have put San Diego in risk of losing Comic Con because the proposed site would have been more than half a mile away from the convention center. Comic Con officials claimed the large separation made the stadium unusable to Comic Con, and believed there needed to be a contiguous expansion of the convention center. John Rogers, Comic-Con board president, wrote a message in the convention's souvenir book that they were opposed to any expansion that wasn't contiguous with the current convention center.
