The Northern Irishman will finish the year as the world's top-ranked golfer after claiming the lucrative FedEx Cup title and the DP World Tour Championship.
McIlroy has been remarkably consistent, missing just one cut while racking up three wins and 12 other top-ten finishes in his 22 starts.
"The next couple of months are really important, as he re-energises and resets himself," wrote McGinley for Sky Sports.
"He doesn't want to lose the momentum he enjoyed in 2022. We've seen him before after quite extensive breaks come out of the blocks slow and kind of lose the initiative a little bit, then try new things.
"It's key that he keeps his focus of thought and to continue working along the lines we saw in 2022 as its a path that has yielded results and him becoming the best edition of a golfer that I've witnessed in his career to date.
"While the measured decision-making has proved fruitful in terms of the consistency of top-10 finishes in all four majors, he will have realised the importance of blending this new approach with flashes of that swashbuckling style of his that draws us all in and separates him."
In 2023, McIlroy will hope to further separate himself by winning a Masters title, the final feather missing from his colorful cap.
