Wynton is a highly educated musician, that made him perfect for Lincoln Center.
He started off in the big league of jazz musicians, not just any musicians, but the big league of jazz musicians, and he blew like big league musicians. After he left Blakey, there were extremely high expectations; it was expected that he would compare to musicians like "Lee Morgan", Donald Byrd, and Freddie Hubbard, but his albums didn't rise to the occasion.
The problem was that more was expected than he could deliver. Now if you read the newspaper, he always got good press, but if you talked to aficionados, and the top jazz musicians, he wasn't in the "creative" running with the likes of Lee Morgan and Donald Byrd.
Fortunately for Wynton, since he could also play Classical, that really put him in good with the establishment; one that really never understood hardbop or modern jazz noway.
The bottom line is that more "creativity" was expected of Wynton than he was able to deliver.
When you compare Wynton to Lee Morgan or Donald Byrd, you'll see where many other top jazz musicians are coming from. The establishment said it was jealously, but they're the last people to ask any questions about hardbop or modern jazz. There was no jealously, just statements of fact.
