I think that's why they should ditch the idea of redoing the play-by-play commentary / new commentators / lines / etc. because of the work it requires, and instead create segments with replays or stat-overlays (or both!) during the game (similar to batter-pitcher duel breakdowns) and add-in new lines for those specific to each game to make them more unique and immersive.
Lines are always going to get repeated in sports games, so until there's tech out there that can create organic, contextual commentary for game situations, I've always felt the focus on this aspect of presentation should be used to showcase the game itself and the storylines occuring throughout the game.
