Question about division races

[Rupert Patrick]

I am reviewing the 1935 NFL season, working out the weekly standings for the season, and I realize in the NFL Western Division that each of the four teams (Chicago Bears, Chicago Cards, Detroit and Green Bay) held sole possession of the division lead at some point in the season. Of course, that is the only division in pro football history in which all the teams finished over .500, and I believe all the teams were still in contention for at least a share of the division title going into the final two weeks. It was one of the great division races in pro football history, no doubt. I am wondering, is it the only time all of the teams in a division have held sole possession of the divisional lead at some point during the season? It must have happened since then, especially with a poor team that wins in Week 1 when the better teams all lose, but I can't think of one.

End of Week #9, 1985, everyone in the AFC Central was at 4-5. Not sure if each team led alone at one point though.
