We don't know what all the details on the inner workings of the team were. So personally what I put together is that Linden, as team President, gets to have ultimate authority over team and organizational decisions, however he wants to use that. But Benning, as the teams GM, is the guy that directly talks to (or delegates) other GM's and players agents.
That original group of Linden/Benning/Desjardins I liked to refer to as the 3 stooges. It was pretty obvious that Benning and Desjardin both had 'their guys' they liked to target, but you can't really say that of Linden who had no experience here and had pretty much no involvement with the game since he retired as a player.
So looking back on it Linden was less a stooge and more a useful idiot. He came in as the boss but as President his view to the league waswas expecting to learn the game from the veteran here, Jim Benning, and while not very adept at the job operated for years under the assumption that the GM was competent. With several years of failure he was at least smart enough to start seeing there was something wrong and started talking to other teams and exerting his authority more It wasn't long from that point that it became a conflict, ownership stepped in and fired Linden siding with Benning.
So while he obviously didn't do a good job whatever happens this is more on Benning and Aquilini than Linden.
