There are at least five quarterbacks who are unpredictable in their play, despite their team's success; some are able to do enough to ensure the success of their team, yet depending on the amount of talent surrounding them.

And some quarterbacks have room for improvement, in which they can take their team even further.

Andy Dalton (Cincinnati Bengals):

  • First 4 games (2-2): 5 TDS, 4 INT, 1,003 YDS, 65.1%
  • Next 4 games (4-0): 11 TDS, 3 INT, 1,246 YDS, 68.2%
  • Last 5 games (3-2): 9 TDS, 9 INT, 1,170 YDS, 57.2%

There's no excuse for Andy Dalton, while his stats don't look terrible, he still needs a lot of improvement in terms of interceptions. The Cincinnati Bengals have provided him with A.J. Green (I don't think he needs an introduction), and other dependable receivers in Marvin Jones, Mohamed Sanu, and Andrew Hawkins.

The Bengals also run a two-tight end formation with Jermaine Gresham and Tyler Eifert; the rookie running back Giovani Bernard is another reason Dalton shouldn't struggle the way he does.

The Bengals' offense is filled with talent, and Dalton's consistency is what will determine the Bengals' success; Dalton may not deserve to be on this list, but with the depth of talent on the Bengals' offense, he can do MUCH better.

Joe Flacco (Baltimore Ravens):

  • First 4 games (2-2): 5 TDS, 7 INT, 1,091 YDS, 59.5%
  • Next 4 games (1-3): 5 TDS, 2 INT, 1,076 YDS, 61.8%
  • Last 5 games (4-1): 8 TDS, 8 INT, 1,071 YDS, 60.1%

Looking back at his postseason performance (11 TDS, 0 INT) which led to a Super Bowl win last season, Flacco has been surprisingly disappointing. The Baltimore Ravens have a decent receiving corps with Jacoby Jones, Torrey Smith and Marlon Brown, all three receivers that any quarterback would love to have on their team.

Maybe the running game is to blame with Ray Rice averaging just 3.0 yards per carry, but something needs to change for Flacco.

Eli Manning (New York Giants):

  • First 4 games (0-4): 6 TDS, 9 INT, 1,148 YDS, 55.6%
  • Next 4 games (2-2): 4 TDS, 6 INT, 1,019 YDS, 55.8%
  • Last 5 games (3-2): 6 TDS, 5 INT, 1,087 YDS, 64.1%

Eli Manning is having the worst statistical season of his career, which is surprising for a two-time Super Bowl winner. He hasn't thrown a lot of touchdowns, his completion percentage is below his normal percentage, and he has thrown plenty of interceptions.

Colin Kaepernick (San Francisco 49ers):

  • First 4 games (2-2): 5 TDS, 4 INT, 856 YDS, 57.2%
  • Next 4 games (4-0): 4 TDS, 1 INT, 728 YDS, 54.9%
  • Last 5 games (3-2): 7 INT, 3 INT, 903 YDS, 57.4%

Compared to his stellar season last season, Kaepernick is having a decent season. The 49ers started the season without their No. 1 receiver in Michael Crabtree; he is now back, and has provided Kaepernick with the weapon needed to make the 49ers look like the 2012 49ers.

Despite the acquisition of Anquan Boldin while Crabtree was injured, Kaepernick still had slight problems staying consistent.

Kaepernick doesn't pass for a lot of yards, and his completion percentage is below average, while he is doing enough to win games, he is still unpredictable.

Carson Palmer (Arizona Cardinals):

  • First 4 games (2-2): 4 TDS, 4 INT
  • Next 4 games (2-2): 6 TDS, 8 INT
  • Last 5 games (4-1):  12 TDS, 4 INT

This is a downgrade from the 2006 Carson Palmer, who threw for 32 touchdowns, and 12 interceptions, yet this Palmer is improving. Palmer started the season on a shaky note, but has seemingly gathered his play, and has drastically cut down on interceptions.

Throughout the season, Palmer has been unpredictable, maybe he doesn't deserve to be on this list, but he hasn't earned my trust just yet.
