Because the Gold Cup was already secured? Well, technically, it wasn't when Bradley submitted the roster, but here's what Frank Yallop said on that situation before Bradley turned in his final list.
"If they win the Gold Cup, run right through it, he (Bradley) might go, ‘I’m ok right now. I’m going to go with another group of guys.’ We don’t know what he’s thinking. We spoke about it and he said there’s a chance Landon might be involved in both."
