that would cost teams millions and millions of dollars each. and a lot of teams lose money to begin with.
you can't really just postpone then extend the season, because the offseason is already short enough. teams have already started training for the new season
the only thing you could really do, is put it all on hold for a month, then play 2 games a week for every week of the season. which most teams do at the beginning of the year anyways. that would suck for a lot of guys because they get no time off during the break, then have to play twice as many games when they come back
just a stupid situation all around made by fifa and their greed for dirty money
