Well quite honestly, with every workout I'm seeing more and more that I'm physically incompetent for this job. I can't run very far or very fast, and if you can't keep up with the plays, then you won't be officiating very long.
And no, it's probably not for me for more than one reason anyway.
I remind myself of one Linesman that I had the misfortune of working the chain gang behind. The guy didn't even shake my hand when the three of us introduced ourselves to the officials, and one incident really irked me about him.
A cornerback from the home team had said in between plays that the down marker showed 4th down, when it was 1st down after the change of possession. The guy snapped back, "You do your job and we'll worry about ours!"
That was rude, uncalled for, and incredibly unprofessional. And I'm guilty of everything I criticized that guy for and then some.
Even if that weren't the case, I still probably wouldn't be officiating until I'm about 100 pounds lighter and more physically capable of doing the job.
