Phoenix Suns' Michael Beasley
Throughout the long, winding road of an NBA season, dependability is paramount.
Teams, coaches and fans are looking for players to bring something close to their best game every night.
Or, at the very least, something close to their average game.
It's that fear of not knowing exactly what to expect when a player steps onto the floor that becomes too much to manage.
The most maddeningly inconsistent players in the NBA are those who tease you with spectacular performances, only to let you down with a series of clunkers.
They provide fans with All-Star moments of basketball wizardry. Then, two days later, they leave those same fans no other option but to scream loudly at their televisions to voice their displeasure.
Denver Nuggets' JaVale McGee
JaVale McGee finished last season averaging the second-most blocked shots per game in the NBA.
Yet his coach isn't always comfortable having him on the floor from a defensive standpoint during critical moments of a game.
Throughout his career, McGee has demonstrated a skill set enabling him to make spectacular plays defending the rim.
He has also frustrated coaches and fans, though, by jumping out of position defensively and becoming a liability on a quest for more sensational blocks.
Offensively, McGee has been similarly inconsistent throughout his career.
He has scored 16 points or more this season in four games. In three other games, McGee has shot 33 percent to average four points on 18 field-goal attempts combined.
Miami Heat's Mario Chalmers
When Mario Chalmers plays well, the Miami Heat are simply unbeatable.
Problem is, for every one great game Chalmers plays, there are a handful of other games where he's not even the best point guard on his own team.
Last season, he scored less than five points in just over 21 percent of his games, despite averaging just over nine for the year.
In the three games the Heat lost this season, Chalmers shot 26 percent from the field on 19 total attempts.
He's averaging 4.3 points, 2.3 assists and 1.6 turnovers in those three losses this year as the team's starting point guard.
Conversely, he has also turned in an 11-assist performance twice this season and scored 11 or more points two other times.
Phoenix Suns' Michael Beasley
When you think of inconsistency in the NBA, Michael Beasley's name comes to mind immediately.
Through 15 games this season, he has attempted 195 field goals while scoring only 189 points.
Beasley opened the 2012-13 campaign shooting 39 percent overall to average 12.6 points. Both numbers are down considerably from the 19.2 points he averaged on 45-percent shooting two seasons ago.
He scored as many as 22 points in his third game this season and only two on Nov. 23 in his 13th. He also scored 34 points in a January game last year at Houston while completely failing to score at Denver in April.
I could keep going with examples like these, but I think we're all on the same page.
Chicago Bulls' Carlos Boozer
Carlos Boozer's greatest strength is his ability to score the basketball. His limitations against taller athletes, however, have made him inconsistent in that department over the course of the season.
He has scored over 20 points in three games this season, as of Nov. 26.
He has also scored four points or fewer in three other games.
Boozer's averages of 14.4 points and 9.8 rebounds this year are solid enough, but he simply doesn't provide that type of production every night.
He grabbed three rebounds in a game at Portland this season and 19 in another one at Milwaukee.
In the 2011-12 playoffs, Boozer also failed to reach double figures in three games against the Philadelphia 76ers, and his Chicago Bulls lost each time.
Philadelphia 76ers' Nick Young
Nick Young has All-Star ability with tremendous gifts. But he frustrates fans with poor shot selection and inconsistent play.
He's a streaky shooter who can't stay streaky long enough to be dependable.
Young has scored less than 10 points eight times this season while scoring 13 points more four other times.
Last season, he averaged 17 points in January alone. He then closed out the season averaging only eight points in April.
In his fifth season, he's coming off the bench for the Philadelphia 76ers to average 9.7 points on 37.6 percent from the floor through 15 games. Two seasons ago, Young shot over 44 percent to average 17.4 points.
