So the 4 division winners plus the next best 2 records min each conference make the playoffs. 2 division winners are stuck playing the wild-card teams in an extra game.
Why not just expand the playoffs to 16 teams, either top 2 in each division make it, or do 4 winners plus next 4 best records (i.e. so 3 teams from one division could make the playoffs)?
Pros are a more equitable playoffs, and more playoff games.
The big con is the stigma of having a league where 50% of the teams make the playoffs, which NFL and MLB fans rag on the NHL and NBA.
