The American league too is improving but that is because of the large number latin american players not the American footballers whose quality is barely conference level.
These Yanks need to be driven from the game as do all the other greedy money hungry Yank owners. It is impossible for any Yank who has not lived a substantial portion of one's existence in Europe to understand Football.
This isn't the lowlife American football league that tore up Wembley and sent England out of the Euros or Ice Hockey. This is a real competition with real supporters and passion no one in the United States understands except certain impeached ex-presidents in the bedroom.
Americans should stick to something they know well like war and leave the football behind.
