When asked "when it comes to closers, who do you think through the years has been better than you?" he responds, Hoffman, Francisco Rodriguez, Papelbon, Joe Nathan, Soria. When asked "you think all those guys are as good as you?", he then responded, "I think they're better than me".
I always liked Mo, he's one classy guy. Check out the interview, he's asked about Papelbon closing for the Yankees and the use of performance enhancers in baseball and he gives some pretty entertaining answers.
