The exact numbers 14/8 are unfeasible in a modern structure, but a very close
12/9 layout already exists.
The problem with 14/8 is that at face value, it's only 44 series, and for it to hit 52 the non-division matchups need to be split into three series each instead of two. In turn, to avoid overuse of two-game series, a ninth game needs to be added to each non-division matchup, hence the schedule above.
