For me, football is the sport it is because its fast paced game with minimal stoppages.
As such, i don't really support the introduction of any technology into the game that would affect this pace. The goal line chip, sure it doesn't take any of the speed out of game or cause unnecessary stoppages. However, when it comes to the aspect of replaying or challenges, i am completely against it. Referees are there to do their job, and the best they can of it. As i play the sport myself, i can attest to the fact you get as many calls in your favor as you do against you. Referees are human, occasionally they make mistakes, get over it. Holding up a game repeatedly to check if the right call was made for me ruins the game entirely.
