Columbus Crew have promoted their game with the Sounders centred around Dempsey's appearance.
"No, I think it's good for the league. I don't think it's anything unusual from anything in the past," Schmid told the Seattle Times.
"The first years of the league you had guys like Carlos Valderrama and Jorge Campos and Roberto Donadoni and players of that caliber selling the league. Recently, obviously you've had a David Beckham doing that. Robbie Keane certainly sells some tickets for L.A.; there are people that want to see him play. Clint is part of that group along with Landon Donovan and some others, so I think whatever sells tickets and gets people into the stands to see our game and to see our sport and our guys, I think once they come there's a chance they'll come back again, so it's a good thing."
