O'Driscoll, who stuck to his guns in the post-match press conference, subsequently put pen to paper afterwards in an effort to get his point of view across.
The former Nottingham Forest boss refuses to discuss the Championship table with the Robins rooted to the bottom, seven points adrift of safety, and insists he is more concerned with his side's performance levels.
"I am acutely aware it's results that will determine our fate this season, and I'm also acutely aware there are people who still don't grasp what I mean when I say I have to concentrate on performances, not results," he wrote in the letter printed by the Bristol Evening Post.
"Surely, at this stage of the season, results are the only thing that will make a difference to our league position. Of course, results dictate everything, and of course, I understand supporters' concerns are only with the results with games running out.
"But how do you just suddenly click your fingers and make results happen if the players don't understand what they need to do to try and win every game they play?
"That understanding is reflected in the performance, so when I talk about performances, regardless of the final score, I'm asking 'Have the players done everything required to give themselves the best opportunity to win that game?'
"The outcome cannot determine how good a performance has been. You won't play consistently poorly and win lots of football matches. Producing a one-off dazzling display and victory - if you don't understand how you did it - won't help you progress."
He added: "When I get asked about not looking at the league table, I don't answer the way I do to try to be clever or difficult.
"We try to win every single game we play. You win more than you lose and the points tally takes care of itself, but the league position may not because what the other teams do is completely out of my control."
