Table schema:
CREATE TABLE postseason (team_id_winner VARCHAR, year VARCHAR); CREATE TABLE team (name VARCHAR, team_id_br VARCHAR)

SQL: SELECT T2.name, T1.team_id_winner FROM postseason AS T1 JOIN team AS T2 ON T1.team_id_winner = T2.team_id_br WHERE T1.year = 2008 GROUP BY T1.team_id_winner ORDER BY COUNT(*) DESC LIMIT 1
