The Seagulls, beaten in the play-offs last season, have won their last three matches and lie two points off the top six ahead of Saturday's visit of Bournemouth.
But Crofts said: "It is too early to talk about promotion, we have played 16 games and we have 30 left so there is a lot of football still to be played.
"The more wins you get under your belt then the quicker you climb up that table, and obviously we have being doing that of late so we want to keep that momentum going.
"Winning games creates momentum and a buzz within the boys that can take you a long way."
