Baseball I think takes the All Star game fairly seriously, or maybe not the game but the Homerun Derby seems to be quite a big deal.
The NBA and NFL All Star games get a lot of criticism for being uncompetitive and uninteresting. Mostly the attempts at defence are half-hearted at best precisely because they don’t want to get injured and in the NFL the best players don’t even play in the game anyway because they have the Super Bowl the following week.
I like that he’s thinking outside the box, certainly there are many things the Premier League and football in general can do better but this one is not the greatest idea.
