Everything I've seen, read and heard about Snider has said that he was "involved" in decisions - but primarily to the extent that his "hockey people" make the decisions, bring them to him and he would ask "so, is this really what you want to do?" and then he would take the advice of the professionals that he hired to do the jobs.
I do think that, for example, in 2010 he said something to the extent of "we need a legit starting goalie" which led Homer to identify Bry
This wasn't supposed to be about whether Snider had "final approval" of the roster - according to Carchidi he did.

Frankly I expected this board to howl with pleasure at being vindicated, if only by a Philly hack reporter.
