As a fan of a very frustrating team to watch in the NBA for the last two or three seasons, consistency matters. A winning team has role players that come through on a regular season. What matters most on a winning team, though, is the consistency of a star player that can show up each and every night. Neither is a factor that the Chicago Bulls have this season.
No star is going to blow every team away. Even the greats like Michael Jordan of the Bulls and LeBron James with the Cleveland Cavaliers, Miami Heat, or Los Angeles Lakers, avoids every off night.
