The Washington Redskins and other advocates of expanded rosters for the 1983 season will resume their quest Wednesday during National Football League meetings near Tampa, Fla.

League officials also will continue discussions regarding the DeBartolo family's involvement in NFL and U.S. Football League franchises.

NFL rosters are fixed at 45 players, four fewer than teams had last season. The Redskins and other teams say by adding four players per team, the league would keep athletes away from the USFL.

Others believe 45 players are adequate and that expanded rosters would result in unnecessary costs.

The roster issue was discussed at length during the NFL's annual meeting, which was held in March in Rancho Mirage, Calif. It was decided then that no decision would be made until this meeting, which could last through Thursday.

The DeBartolo problem also was discussed in the March meeting. The league is upset that Edward DeBartolo Sr. has been awarded a franchise in the USFL while his son, Edward Jr., is the owner of the San Francisco 49ers of the NFL.

In March, the younger DeBartolo was asked to talk to his father about the latter's USFL plans and then report to NFL Commissioner Pete Rozelle. Since then, DeBartolo Sr. has become the owner of the Pittsburgh team in the USFL, creating what many in the league view as a possible conflict of interest. However, Rozelle admits he isn't sure what the NFL can do about the situation.

It is also expected that officials will discuss the possibility of switching the draft from April to February, although a final decision might not come until fall. The Redskins are one of the teams pushing for a change in draft dates.
