The source for the first part of the request is not a relaible source. It is a testimonial-like piece advertising the services of John F. Murray. The reference for your second part is a google search. The first Tribune hit merely mentions "giant-killer Vince Spadea" without explaining the term. The second hit uses "upstart Vince Spadea", and I wouldn't use it as a source to say that the Tribune calls him an upstart.
