I think ESPN likes the schedule exactly as it is now because starting later would interfere with broadcasting the baseball and softball playoffs, which have higher ratings.
broadcasting lacrosse games is not a huge cash cow now or for the forseeable future.Wish there was schedule expansion and the season went longer with more games (and started later.)
Could be a huge cash cow for the networks and NCAA if they chose to market it and with NIL here to stay I think everyone involved would be on board.
