You asked closed-ended questions, friend. An open-ended question to what Ellis taught? How about nearly every single pass-rush move that Ware utilizes now? How about the balance that he taught Spencer? How about the lessons about transitioning to OLB that he taught Spencer?
He may not be a tremendous player, but again, considering that you hear probably 1/10,000 of the conversations Ellis has with his teammates, I would tend toward the belief of someone who would have actual evidence of his leadership. Ellis has been reasonably successful because he has decidedly above average technique, but he is physically inferior to both Spencer and Ware, and aging sufficiently that his technique is no longer enough to sustain him.
He taught Ware how to not win a playoff game? Come on, do you really think that wasn't a disingenuous, ridiculous kind of pseudo-question to ask?
