One of the first big names in independent wrestling to be mentioned in the dirt sheets and PWI. Seemed like Quack, Reckless Youth, and Christopher Daniels all missed the boat when WCW/ECW died, but the ship sailed so they tried to make the dock a destination instead.
Mike's biggest contribution to indy wrestling was certainly Chikara and the King of Trios Tournament, which helped develop the careers of many young talents as well as a platform for talent who otherwise would have been considered too old to perform.
Quackenbush-Kingston was as fitting a coronation for a Grand Champion as possible, and a fine match. Sending Sara Del Ray out there to fend on her own against men sometimes twice her size was something to behold. Viewing the antics of Archibald Peck from show-to-show was always a highlight.
I can't really speak to his training efforts, but based on his in-ring contribution and his desire to release a quality product when the opportunity provided, I would say Mike Quackenbush is the kind of wrestling mind the business could use more of on a wholesale level.
Maybe even someone who will need a closer look under the microscope, as I can't recall too many DUDs or classics.
