ABC used to air postseason games during the week
I believe they did that for round two. Same with NBC. The biggest problem is hoe ass ABC tries to drive viewership to ESPN so they will only put a couple of games on ABC on Saturday/Sunday and and drive the rest of the viewership to ESPN.
Where as when NBC had the NBA they had no problem putting a triple header on Saturday and Sunday without having to change a channel.
Also when TNT exclusively had the NBA they would have first round NBA games on at the same time on TNT and TBS.
NBC was far better at promoting the sport and showing constant commercial for the upcoming games during the playoffs. ESPN doesn't do that really and especially don't do it on ABC for the upcoming NBA playoff games that are airing on the ABC channel.
