It is a fact that owners who are more meddlesome are usually less successful.
Jerry Jones is one of the most involved owners in all of North American sports and the 'Pokes haven't won shit in forever. Not since the dynasty built by Jimmy Johnson and Minnesota Vikings' ineptitude that was so strong, any yahoo (yeah, I'm looking at you Barry Switzer) could win with it, petered out.
James Dolan of the Cablevision family empire is the principal owner of both the New York Knicks and the New York Rangers. He fancies himself a basketball aficionado and for him, hockey is an afterthought. He's constantly involved in the affairs of the Knicks but he lets the professionals run the the Rags. It's no mistake that the NHL club is a model franchise with loads of success in the decade and a half Dolan's been in charge and the Knicks are an embarrassment over the same period.
Other meddlesome owners are the bosses at some of my other favorite teams. Robert Sarver fancies himself a genius who must have input on all the basketball decisions his Phoenix Suns make and that franchise has been rudderless since he's owned them. American businessman Malcolm Glazer doesn't know shit about proper football (soccer) but he insists he rules the roost at Manchester United and that his buddy, Ed Woodward, another American that doesn't know jack all, run the operations of the club. Finally. no-one's more interfering and overbearing than Daniel Snyder who may in fact be the worst person in professional sports ownership today.
In short, my point is that Arte is indeed "free to have input whenever he wants in any decision he wants." He's also free to realize he doesn't know thing one about running a professional baseball club and should be smart enough to refrain from being intrusive. After all, I doubt he'd want Jerry Dipoto, Billy Eppler, Tony Regins, etc. telling him how to make and sell concrete.
