Brown gave no hint he was under pressure after losing in front of incoming chairman Adam Pearson.
He said: "I think what went for us was the commitment of the players, that's the first thing I will say.
"In terms of a manager asking for a committed performance from a group of players who were under pressure because of the situation that we are in. I don't think anybody can question that.
"Yes decisions have gone against us, probably four in total which tends to lend itself to something else. But we're not here to talk about that.
"With that kind of commitment and that level of performance from my players we'll be fine this season but we have to put a run of games together.
"We've got a big game against Stoke next Sunday and the one thing you need in your locker is commitment."
