The Londoners remain in the bottom half of the table after winning just two of their last 14 games.
But Jol was happy with the spirit displayed as his side staged a late salvage act at freezing Bloomfield Road to snatch a place in the fourth round of the FA Cup at the expense of Championship side Blackpool.
Kieran Richardson struck an equaliser in injury time and Brede Hangeland settled a largely unremarkable replay 2-1 in dramatic fashion the 116th minute.
Jol said: "It is about a little bit of quality and character and we showed a lot of character.
"But sometimes we need a little bit more urgency up front.
"In the first half we had two or three very good opportunities and you have to take pressure off your team. That is a responsibility you have got and that is what we lack sometimes.
"In the first three months we were scoring goals for fun and now, over the last five, six or seven weeks, we have had problems scoring goals."
