Freedman's side are eight points off the play-off and just seven clear of the Championship relegation zone after losing 1-0 to Sheffield Wednesday.
It was their second successive defeat after lost to Wednesday's relegation rivals Peterborough on Saturday.
Freedman said: "I thought that we didn't put enough pressure on Sheffield Wednesday's goal in the first half and that ultimately cost us after going behind.
"In the second half we put them under a lot more pressure and upped the tempo but over the 90 minutes we didn't do enough.
"I put the defeat down to their good defence, which we couldn't break down and the consistency of our results is not where it should be at this time.
"It does surprise me that we are so close to the bottom but it doesn't concern me because I've seen what this group is capable of.
"I think the players need a bit of a hand and we need to recruit two or maybe three guys who have played at this level before.
"The club as a whole is suffering from a bit of a hangover after getting relegated, but I'm sure when we get the right personnel in we will start to get a decent run of results together."
