Since LeBron is an elite athlete, probably among the top three in the game today, it's understandable when a player of his caliber is considering changing teams. Although It's all about the money, his decision has a huge financial impact on the team and city where ever he decides to go. So yeah, it's kind of a big deal if you're into sports.
This is nothing new since there are thousands of instances where the sports media went into a frenzy over someone's new contract, will be the first player drafted, a player's infidelities, drug use or personal issues, a coach raping young boys in a locker room, etc., etc., etc. Just wait long enough and the LeBron news will be old hat and we've moved on to the next "sports issue."
