With the news of Kevin Towers being fired from the D- backs, I was curious about what he did to get the ax. His first season as GM he did a 180 with the team and made the playoffs after a terrible year prior. He then had a couple 500 seasons before this year's freefall. My off-handed assumption was that he made some pretty bad deals. Looking at those deals more closely, they weren't very good, but weren't the worst either. So I started reading a little this morning about GM rankings, firings, ect. I came across this article about GM rankings prior to the 2014 season; complete with a spreadsheet showing some of the formulas used (though, I would have preferred a better explanation for some of the values given. I thought it was strange that in a game where everything is tracked and mapped, GM success is not. For example, I would think that the net-value of WAR in a trade could be an indicator of how well that trade worked out for your team (of course, you can debate the use of WAR for this and how reliable an indicator it would be). Other factors I believe should be involved are revenue, success during regular season, success in playoffs, FA WAR, money spent on FA, players drafted success, drafting position, WAR of players after leaving organization. A few of these are covered in that article, but I believe it was a half-hearted attempt. In case you don't want to click the link and read through it all (normally guilty of that), Terry Ryan is given a rank of 18. I thought it was a fair ranking. Especially coming into the season. Now, I think the rankings would be different if given now. A bunch of the GM's ranking below Terry Ryan in this article have had pretty good seasons. Since many don't know them, I'll post teams with them Michael Hill (Marlins), Dan Duquette (Orioles), Doug Melvin (Brewers), Jerry Dipoto (Angels), Jack Zduriencik (Mariners). I was actually surprised I was familiar with the GM's in the MLB after reading threw them. So, while Terry Ryan ranked 18th, a case can be made for those GM's to rise in these rankings. Maybe not necessarily passing him in all cases, but improvement for them nonetheless. At the same time, the Twins looking at another fallen season, the Twins apparent detachment from their fan base, all point to the continued demise of the ship Terry Ryan is sailing. What do you think? The Terry Ryan topic is a horse well beaten on this forum, but looking at GM rankings is kind of a different perspective and I'd love it for some of our more mathematically gifted posters to attempt it (I don't have time, sorry guys).
