You would have to transfer twice, taking 3 different buses, so it can take up to 2 hours: CR to DHS, DHS to Pop, Pop to ESPN. The bus to ESPN runs only every 30 minutes.
You'd probably be happier taking Uber or Lyft. If you want to lower the cost, take the bus to DHS and summon a ride from there.
Plan to arrive at least 30 minutes before game time, as pre-game traffic into the complex can get pretty bad.
