NFL owners will convene today in Orlando, Fla., with the collective bargaining agreement extension behind them and the search for retiring commissioner Paul Tagliabue's successor ahead. While a commissioner search committee might be formed during the three days of meetings, there also is other business to address. Returning to Los Angeles, from which the Rams and Raiders both bolted after the 1994 season, has become a staple of these annual spring meetings, as are tweaks to player safety rules and the instant replay system. In the wake of Pittsburgh becoming the first sixth seed to win the Super Bowl, Kansas City is proposing yet again to expand the playoffs from 12 to 14 teams. And Tampa Bay is proposing to make all penalties subject to instant replay. "Moving forward on Los Angeles is a key priority ... because the economic foundations that enable us to look at that type of a challenge and to address it are in place with TV in place and labor in place," Tagliabue said. Tagliabue continues to meet with prospective ownership groups, whose team would play at the Los Angeles Memorial Coliseum (the former home of the Raiders), the Rose Bowl in Pasadena or at Angel Stadium (the former home of the Rams) in Anaheim.
