yes, they should.
as a pro you should be required to present a physique that is worthy of being a pro. You're not a pro baseball player for life, you have to uphold a certain standard or you are cut or sent down to the minors, same with every "sport" that matters.
you get a line up and you get a few decent guys at the smaller shows and the rest are also rans, ham and eggers or whatever. I say if you haven't been top 10 in a show for 2 years (and have competed during that time or if you have not entered a show in 5 years) you should be required to enter a show and have a respectaible showing if not you need to requlify to be a pro.
