Mike Trout has not had the best season ever, and neither have the Angels (obviously). Trout missed a month from injury, but his performance in the second half of the season highlighted by a month long home run drought had a lot of fans worried that the greatest Angels player of all time was truly heading towards the twilight of his career. And apparently, there are people inside of the Angels' organization who share that concern.
Sam Blum of The Athletic noted in a feature about Trout that there are concerns among Angels employees that Trout's long-term value may be diminishing.
