Bill James did an article on the Angels which should interest Trouty...
Here are the synopsis of the two most recent era's of Angels history:
5. Salmon, Scioscia and Moreno
1997 – 2009
In late 1996 Gene Autry stepped aside, and In 1997 Terry Collins took over as manager of the Angels. Collins had managed successfully in Houston. The Astros, who had not had a winning season since 1989, produced four straight winning seasons for Collins (1993-1996) but collapsed late in the season in 1996. Collins was an intense man at that time, a high-pressure manager, and some people felt that he was too high-pressure.
The Angels took the good with the bad, began to move up. The Angels’ results with Terry Collins were similar to the Astros’: a couple of good years, and then the players started to get tired of him. Collins was replaced by Mike Scioscia.
This is recent history now, comparatively. I’m sure you all remember Mike Scioscia’s good years. The Angels won 99 games and their first (and only) World Championship in 2002. Artie Moreno bought the team from the Disney Corporation in 2003, and announced immediately that "we are a big city franchise and we need to act like it." With strong leadership from Scioscia, Moreno and GM Bill Stoneman the Angels won 92 games in 2004, 95 in 2005, 89 in 2006, 94 in 2007, 100 in 2008 and 97 in 2009. Although they never got back to the World Series they were in post season play just about every year. By 2009 they had a Franchise Strength Index of 85, and were the fifth-strongest organization in baseball.
6. The Mike Trout Era
2010 to the Present
And what has happened since then?
Well. . .I don’t want to be judgmental. The Angel organization has not gone into the tank, but entering this season—despite having had the best player in baseball for most of this decade—the Angels Franchise Strength Index was down to 78, and did not appear to be headed up.
There is a special problem for teams that play in the largest cities. I’ll write more about it when I get to the Mets, but it has to do with what we could call glittering options. When Albert Pujols was on the free agent market post-season 2011 he was a glittering option. When Josh Hamilton was available a year later he was a glittering option. The Angels didn’t ask "Is this player actually going to help us?" They asked "Can we afford him? Well, hell yes, we can afford him. We’re a big-city franchise here!" This leads to an unwise allocation of resources.
The Angels have kind of wasted the Mike Trout years, frankly. They haven’t collapsed, but they have not built around him. Yes, they have had some terrible luck, but they have not done what they should have done with Mike Trout in the lineup.
