While he was forced to contend with the loss of Daniel Sturridge and Philippe Coutinho's lack of fitness, the result was still far from ideal for a team chasing a top-four berth in the Premier League.
Per the Press Association's Rory Dollard, via the Daily Mail, Rodgers said:
Disappointing is an understatement. We went into the game with confidence and belief but we made too many mistakes with and without the ball.
We lacked quality with the ball, we never created enough and never kept the ball long enough. I always felt we were in control of the game but we needed to show more quality and penetrate a wee bit more.
That any team should feel the loss of a first-team striker, or indeed find life difficult away at Hull this season, does not mean much in itself.
However, Rodgers will realise that his side's only win in their last four league games came against relegation candidates Fulham. After a bright start to the season, it is now imperative that they quickly respond to what has been a brief setback in recent weeks.
After what was a lacklustre performance against Hull, the Northern Irish manager's comments are a call to arms for his players after another game where the midfield, in particular, will feel they could have done better.
Sturridge's absence will get plenty of attention, with BBC Sport reporting that he faces six to eight weeks on the sidelines as a result of the ankle injury suffered in training.
With Iago Aspas also lacking match fitness and Fabio Borini on loan, the doubts over Liverpool's depth in attack that were raised at the start of the campaign are now beginning to cause real problems.
Luis Suarez aside, it is now difficult to see where Liverpool can look to for a frequent source of goals—with Victor Moses yet to add to the solitary goal he scored in the opening weeks of his career at Anfield.
With the January window still a month away, Rodgers will have to coax results out of his existing squad until he is able to sign reinforcements. Without strength in attack, he now desperately needs some of his big-name midfielders to up their level once more.
