Don't get me wrong, there's nothing wrong in liking Elliot or Marshall or all of these guys. Absolutely amazing/killing players and I admire all of those guys. But from what I experience and what I hear in lots of young players playing is that they studied a lot of Michael Dease or Elliot Mason and didn't care about where those guys took their inspiration from which usually are like JJ, Carl or Frank and unfortunately you can hear that the foundation and the roots of that are missing. I really had to push some of my students to really get away from listening to some super virtuous Marshall solos to check out some clear and easy JJ stuff, because they were trying to get crazy high stuff going without having any foundation about what to play on simple changes.
When I've been studying (which is not too long ago as well to be fair), I basically exclusively listened to Carl, Frank or Curtis (later on lots of Albert Mangelsdorff) and had lots of albums by those guys laying around. I might have had one album of Marshall or Elliott and that's it.
Am I wrong about this? Is this normal to a certain extent? Does it do any "harm"? Would love to hear from folks working with young jazz players how they feel about that.
Edit: All names mentioned are just examples of course. Add other names to it if you want.
