Lax, I like your argument, except for the middle part. Trout set such an incredibly high bar during the summer that people are overexagerrating this "slump" at the end of the year. Over the past month he still hit .284, with a .402 OBP, 22 runs, 5 homers, and seven steals while still playing his fantastic D.
It is also not his fault he did not play a full season - if anything, that should help his argument and not hinder it. He was a revelation from the moment he came up, and jump started his team to the best record in the AL during his time on the team (Thanks Sherm for the clarification).
Finally, Trout not going to the playoffs while Carbera is really shouldn't decide anything. #1, as mentioned above, Trout has led his team to the best record in the league during his time in the majors. #2, the Angles HAVE A BETTER RECORD. It is not Trout's fault that his team plays in a tougher division, or that his pitching has been much poorer than anyone expected. The Tigers definitely do not make the playoffs without Cabrera, but the Angels do not have the better record or come anywhere close to contending without Trout. Period.
