In theory, yes ... but, in reality, if you're thankful for what you have in life (and God knows Lesean McCoy has it), you try to remember that.
Hell, I tip my barber $5 a cut, the pizza delivery guy the same. And I don't have McCoy's money.
Foo Fighters' Dave Grohl tips regular people $1,000 ... I'm not saying McCoy should do that, but Grohl gets how fortunate he is. Others should too, IMO.
