Going back to 4 teams, or turning the current wild card game into a 3 game series are much better options than what is proposed.

Teams were way more inclined to go for it and make big trades at the deadline when the Wild Card spot was worth more than a 1 game crap shoot.

Starting the post season with odd numbers of teams in each league just feels weird and forced. 7 teams? If we must add teams, how about we go back to an East and West with a balanced schedule, 6 teams make the playoffs in each league, 2 best of 3 series for the bottom 4 (like the normal season), top 2 get a bye.

Rewards the division winner appropriately, and the 2nd and 3rd best get home advantage.

The picking of opponent stuff is way too gimmicky.
