Lack of dedication. There was a lot of politics that showed up playing in college, the best players weren't out on the field, and the team knew it. But the people in charge made those decisions, and it ruined a lot of the "best players on the field should be playing" in my opinion.
Do I want to dedicate my physical longevity to this sport, or do I want to be able to run around with my kids when I'm 40 played a lot into it as well. There is a lot of physical activity that was required that I didn't want to do to my body. I decided to earn money with my brains, not my body.
I have to say even with millions of dollars, Trout is stuck doing the same thing every damn day, and I don't know if I was down for that. For example I just spent the last 6 days at Disneyland, California Adventure, Knott's and Magic Mountain and I wouldn't be able to do that if I was playing ball. That freedom to hang out with my buddies is priceless.
