Frogman, as always, your post is 'technically' correct, but in the looser artistic sense I disagree with it.
Diz and Bird, 'technically' correct in regard to "Bebop" the new jazz that progressed into "hard bop"; but in regard to Lee Morgans prodigious creativity in jazz that stayed in the mainstream of jazz without 'flip flopping' all over the place like Miles who was always searching for a new audience, I will take "Lee Morgan" any day.
While Lee Morgan idolized Clifford Brown (everybody did, and that includes me) it wasn't Lee Morgans fault that Clifford didn't live longer, and that he Lee Morgan should have such a large output of creative jazz that has withstood the test of time and brought him into the top ranks of jazz trumpeters of all time.
As I stated before, when I chose Clifford Brown over Lee Morgan, it was because I hadn't heard enough of Lee Morgan; now that I'm listening to Lee Morgan, I'm amazed at the new creativity that pours out of his horn on each album without ever being repetitive.
Enjoy the music.
