Re: Postgame actions of football and basketball players as opposed to baseball player
Hockey players always form a line and shake hands with their opponents after the final game of a playoff series. In the NFL it seems optional - much like baseball. Although players do sort of informally congratulate each other and sometimes pray together. You don't see it in baseball past college.
Although you can't say LeBron is a phony. He may be a poor sport but you have to admire him somewhat for taking the loss so hard.
