Great topic, but I haven't heard much of anything tangible on anything happening.
Personally, I'd like to see the Power 5 Conferences all go to 16 or 20 teams. Divide each of the 5 conferences into two 8 or 10 team divisions (This is for basketball purposes only, not considering football impact). For the 10 team division option, each Conference play a true round robin for each division (18 game conference schedule). If the 8 team per division option, then true round robin in division (14 games), then either 4 or 6 games with teams in the other division to get to a 18 or 20 game conference schedule. Then take the top 8 teams from each division to the conference tourney.
