What Should Happen: Defending region and Maryland 3A champion Gwynn Park (19-1) enters the postseason with a chance to become the third team to win consecutive 3A titles in the 31 years of the state tournament. Though Gwynn Park is seeded second behind Howard County champion River Hill (18-2), the Yellow Jackets defeated the Hawks in the IAABO tournament, 64-59, on Dec. 26. Entering the week, Gwynn Park had won 13 games in a row, and its 20 opponents had scored 36.6 points per game.

What Could Happen: River Hill may have lost to Gwynn Park in December, but the game was tied at 45 entering the fourth quarter, proving the Hawks to be formidable challengers looking to win their first region title. However, River Hill has lost to Prince George's County teams each of the past four region tournaments. Gwynn Park ended River Hill's season last year with a 58-49 victory in the region quarterfinals.

Toughest Draw: After a first-round bye, sixth-seeded Douglass (9-10) plays at third-seeded Mount Hebron (16-3) in the quarterfinals with a possible semifinal game against Gwynn Park and a region final against River Hill. Those three teams entered the week with a combined record of 53-6.

6Teams in the 3A East that had won more than 63 percent of their games entering this week: Gwynn Park (19-1), River Hill (18-2), Mount Hebron (16-3), Severna Park (16-4), Annapolis (13-6) and Long Reach (12-7).
