Must have been pretty shit for them. I didn't boo them personally. But how else can we let them know they're letting us down? I've paid good money for my season ticket. I didn't see a nix goal or a win. If the boos motivate them to play better and it turns our season around then maybe it was worth it.
They're competitive sportsmen. When they lose, they're letting themselves down and by proxy us. Think they know that already without a bunch of childish boo's.
