I think the distinction he might have been trying to make is that Gibson was a bench coach and hitting coach in the majors before being named Manager and Hinch held no coaching or field jobs...
It was considered a very unusual move and was pretty controversial in Phoenix when Byrnes made the move - Hinch was a rising young baseball executive with playing experience in the majors and Brynes believed he could handle it...
I agree that being a good player has nothing to do with being a good manager - all we need to do is look at the managing career of Ted Williams to see it doesn't always work - and even Tony Gwynn has struggled to find success at the college level -
The league is filled with great managers who had no real playing career to speak of
Bobby Cox, Tony LaRussa, Tommy Lasorda, etc, etc, etc
Again the guy just has some major issue with Byrnes and Hinch
