Listening to the Test Match Special commentary (on the cricket match currently underway between England and Australia), I heard the commentator Henry Blofeld complain that the English batsman -Wood- had given a rather "wooden performance". He followed it up with "to employ an eponymous description".
Was this a correct use of eponymous? The expression "wooden performance" already exists - so he wasn't coining the term by use of the subject's name. Had he described a performance by Jones as a Jonesian innings - that would have been eponymous. I would have said he had created a pun rather than to have spoken eponymously.
Purely incidental to this faux pas, Blofeld himself has a curious connection with the eponymous. The name of the master criminal, Blofeld, who appears in every James Bond thriller, was created by Iain Fleming after the name of Henry Blofeld's father - the two of them having been at Eton together.
