Michael Appleton believes he has learnt plenty about his squad after this afternoon's 2-1 home defeat to Charlton Athletic.
The Rovers boss took charge for the first time but watched on as it was Chris Powell's Addicks side who claimed all three points at Ewood Park.
"It was frustrating, but it was helpful," Appleton told Radio Rovers after the game.
"It has given me an idea of the players who are going to be able to cope with the pressures that come with playing for the football club.
"I've just said to the players that we are a big fish in a smaller pond to what they were used to playing in last and previous seasons and you've got to be able to cope with the pressures that come with that.
"You've got to be brave, you've got to want to get on the ball, you've got to play with an urgency and we struggled a little bit today with that.
"Also you've to keep it nice and tight and the goals that we've given away, one is a wonder strike, but the second one was disappointing to concede."
Rovers responded well after Dale Stephens' first half stunner with Jordan Rhodes heading the home side back on level terms minutes into the second half, but Rovers couldn't build on that to turn the match in their favour, poor defending lead to Kermorgant heading the visitors back in front, a lead they would go onto hold.
"The plan was to get a goal back as quickly as we possibly could and Jordan does that so the impetus was with us and for four or five minutes we were on the front foot," added the Rovers boss.
"But I don't know if was down to nerves or anxiety but the players have to ask questions of the opposition, they have to put balls into the box and that is what we will look to do.
"But the manner of the second goal was disappointing, it took the players a long time to get over conceding that."
