I am reminded of coaching soccer, U14, we had a very good team at the rec level, basically mostly good players who could play select or HS but just wanted to have fun. We played another team that had maybe one or two guys who had even played soccer, they were from a disadvantaged area, I thought it great they were doing this, but they were woefully overmatched. At 3-0 I was trying to get my 2-3 not good players up front to get a goal for them. My goalies had lay down on the field, I told him to get up.
At 6-0, I told the team to kick the ball to the other team without looking too obvious. My goal then was to let them score, somehow, but we never managed it, even trying out best.
I'd guess in the above case, it was before helmet radios, and the kneel down play was something done ad hoc, maybe even the coach signalled it in, and then changed his mind. Usually in football you can sub in your scout teamers and let them play and it would be close to even.
