IMO, if they are going to change the format of the season, they may as well expand the regular season to 18 games, and only 2 pre-season, i don't like the odd number of games as it means some teams getting an extra home game which is usually an advantage. and each team, again IMO, should have equal home and away games, all teams get a bye week after games 6 & 12(or 7&13), do away with thursday night games, and make them on a saturday instead.
for playoffs, again don't like the odd number teams, so might as well expand to eight teams from each conference, division winners get home advantage and 1-4 seeds, and home advantage stays with best seeded teams, and start as;
seed 1 V seed 8
seed 2 V seed 7
seed 3 V seed 6
seed 4 V seed 5
edit) maybe add in a bye week after last reg season game so all teams get a weeks rest before playoffs
