I may be wrong, but don't most TDs pay a middleman umpire to schedule umps into a tournament? That person is losing a gig (and relationships with umpires who he would schedule). I assume tournaments in the past have folded the cost of that 'service' and relationship into tournament costs, so this isn't a new service/cost but a replacement and at a drastically higher rate. It probably will relieve some tournament directors that are less experienced from the burden of hiring umpire assignor/umpires, I would assume.
