MIAA and BCL Basketball Playoffs Set: Full Brackets, Matchups, and Championship Schedule

The Maryland Interscholastic Athletic Association (MIAA) and Baltimore Catholic League (BCL) offer one of the most unique setups in the United States as they are two separate conferences with separate championships, yet they share a large core of teams.
The MIAA A Conference is the larger of the two as it consists of 12 teams from the greater Baltimore Metropolitan area, including the seven full-time members of the BCL, as well as new BCL associate member St. Mary's, which competes in the MIAA B Conference.
Confused?
Well, it is a little tricky to decipher as all of the regular season meetings between BLC teams count in the BCL standings, while only about half of those same meeting count in the MIAA A standings. It all depends on whether the BCL teams are in the same MIAA division. It they are, both of their regular season meetings count in the standings for both leagues, while teams in opposite MIAA divisions, only have one of their meetings count in the MIAA standings.
Fortunately for fans who have not yet deciphered the formula, the regular seasons in both leagues are complete and the postseason tournament brackets for both the MIAA and BCL are set.
The A Conference goes first with quarterfinal action beginning on Monday, with eight teams having qualified for the league playoffs. Here are Monday's quarterfinal matchups:
