When starting a historical game when roster is filled with 40+ players, many star players lose their jersey number to half and one star players.

Mike Rogers #71 in Hartford, lost #17 to a player they released.
Bryan Trottier #91 losing #19 to Yvon Vautour.
Anders Hedberg #51 losing #15 to Dean Talafous.
Michel Goulet #61 losing #16 to Pierre Plante.

Those are just a few examples from starting a game in 1979.

It's not game breaking, but still. Would be nice if players with numbers set in database are locked, so players without a set jersey number, can't get those numbers.
