Ringo did more than just provide the necessary backbeat, as important as that is. Young drummers---who have yet to learn the wisdom of not "over-playing"---are quick to dismiss "feel" type drummers like Ringo (and Charlie Watts). But get them into a recording studio and they quickly find out how hard it is to provide truly "musical" accompaniment to a good band. The drummers in more bands than you would believe are replaced for recording sessions by studio drummers who know know how to "play for the song", not their egos.
Tom Petty’s original drummer Stan Lynch recently stated in the great book Pledging My Time: Conversations With Bob Dylan Band Members that only after interacting with studio great Jim Keltner, and the passage of time, did he realize that his drumming was "too busy." The number one complaint by singers and songwriters about drummers is their propensity to over-play. As good as Keltner is, Leon Russell asked Elton John to dismiss Jim after recording of the Union album had commenced. Jim's playing was too busy for Leon.
Ringo is belittled by non-musicians far more than by other other drummers. One of Ringo’s biggest fans and defenders is Gregg Bissonette, one time drummer in the Maynard Ferguson Big Band, and 2023 winner of the Modern Drummer Magazine Best All Around Drummer award.
Buddy Rich described Ringo as an "adequate" drummer, which coming from Buddy is a compliment.
