Kenny Aronoff (best known as John Mellencamp’s drummer in the 80’s-90’s) is a very well educated and trained musician (check his history on wikipedia if interested), yet is imo a very boring drummer. "Stock" parts, nothing special. Springsteen’s drummer Max Weinberg reads music (required to play in a Broadway pit band as he did prior to being hired by Bruce), yet is a complete bore. Very pedestrian, no imagination, no identifiable style or personality.
Band drummer Levon Helm was completely self-taught, but learned the 13 basic rudiments (the equivalent of tuned instrument scales). That enabled him to play a press roll---about my favorite type of drum "fill", as employed to great effect in "The Night They Drove Old Dixie Down". Roger Hawkins (Muscle Shoals drummer, heard in all the great Atlantic Records albums produced by Jerry Wexler---Aretha, Wilson Pickett, etc., as well as in Paul Simon’s "Kodachrome"---a killer drum part, and Box Scaggs "Loan Me A Dime") played as good a press roll as I’ve ever heard (as good as Buddy Rich).
Ringo Starr was (and remains) unable to play the press roll, never having learned the rudiments. That restricted his ability to progress technically, but he’s done "okay" in spite of it ;-) . The Beatles may not have sounded as good if they had a technically better drummer. His creativity and imagination served he, they, and their music well.
