This is for people who want the playoff logos on their own gamedata.
Here's what you're gonna do.
You import the BMP texture using JerseyEditor. Yes only JerseyEditor. Not Modtool, not 3d Tool, it must be JerseyEditor.
Open your gamedata with JerseyEditor.
Select Texture 98.
Then drag and drop the texture you downloaded, then it's done.
Here's the link to the JerseyEditor
