No, it's just a thought experiment....but, consider Page's "competition"; Beck, Townsend, Clapton, HENDRIX, etc.
He's farther from "greatest" guitarist than Bonham or Plant are from greatest drummer / singer. I think a poll of rock journalist would agree (would love to see one).
JPJ is the wildcard. His list of rivals is pretty short at bass. Now throw in his mandolin / melotron / guitar / (name the instrument) prowess...he's also a force.
There's a legit argument that Page is least talented which speaks to the unreal talent in that band. Off the charts.
That is a better way to phase your argument. Thank you.
Just picking one potential rival, though...
You already put Townshend on that top rock guitarist tier.
Moon would be on the same uber tier as Bonham. I am sure any poll of rock musicians or critics would agree with that statement about the two. My personal Mt. Rushmore for rock drummers is Moon, Bonham, Neil Peart, and Stewart Copeland.
Entwistle would be much the same as a bassist.
Daltrey would be as a vocalist.
So that is another right there.
