so last November, the NBA announced their partnership with SAP to provide big data on player stats using SportsVU to track every move of every player (read full story here).
NASCAR is doing something similar, but they are going further by putting RFID chips on the pit crew people to track every movement. with cameras, you will get blocked by objects, but with RFID chips, you can see every move.
why can't the NBA and soccer leagues uses RFID chips on athletes, coupled with SportsVU type cameras and then simply fire every referee? bad-calls be gone!
