Romano,I think that you meant 1.74m(metres),not 1.74cm.(centimeters). If you were 1.74 cm.high,you would be Chuck's height and you would have to live under a bridge somewhere.
Height certainly isn't a relevant requirement to be a good official,as far as I'm concerned.However,I have heard that the NBA is now looking for certain physical requirements for new officials,which I personally think is dumb.If a guy can do the job,he can flat out do the job.If he/she can get in position,make the calls and keep the game moving and under control,it shouldn't matter if he/she looks like ET.Some of the best college and pro officials that I have seen have been short,skinny or slightly overweight,rumpled-looking,etc.Didn't stop them from doing a great job.
