Age, financial security, are probably issues. Never been in positions like him and other players, so I will just speak for myself.
To earn as much as they do, and have the prestige of playing pro, coming from a low social strata background, and the financial struggles that come with that, I'd differ. Like anybody, I like having mo' money, but there's a point you realize you have it made, and hugely better than most. I'd be thankful, keep working, look forward to a retirement in which I can afford to do practically whatever I want, go wherever I want, and thoroughly enjoy a retired life. Being the simple guy I am, for me that'd likely be fishing, hunting (I'd love to take a moose) and eating what I catch or kill. I don't need to show off in some fancy city, having eight cars, a suit that cost as much as a Cadillac Escalade. I'm just fine with Levis and wrangler denim-ware, either Redwing shoes/boots, or whatever is sold at Sears, or even Walmart.
