Joe Schmidt's winning formula may have delivered two Heineken Cup crowns, as well as the PRO12 title and the Amlin Challenge Cup last season, but the new plans aren't doing too badly so far judging by Leinster's first round win at the Ospreys
"It has been tricky the last few weeks getting to grips with things. Matt has pretty much changed everything. Which is no harm," admitted Kearney.
"It sharpens up everything. You play a different brand of rugby and you become a little less predictable to the opposition."
One player who has flourished under the new regime has been Kiwi import Jimmy Gopperth. He won he nod over new Irish outside half Ian Madigan for the No 10 jersey for the Heineken Cup opener in Swansea and turned in a magnificent performance on his debut in the tournament.
The 29-year-old Gopperth was revealed as Leinster's 'Player of the Month' for September this week and is hoping to make another big impact when he makes his home European debut against French champions Castres Olympique.
"Any time an outside half has a real quality all-round performance it's something to be marvelled at because it's not an easy position to play. So, from that perspective I think Jimmy did really well," added Kearney.
"And, likewise, Ian Madigan against Cardiff - he was awesome that day, too. They need to remain as positive as possible and ensure that their attitude when they are not being picked is for the greater good of the team. Once we get that from the two of them we will be in a really strong place."
