Since they introduced it last season, expanded review in MLB has had a real issue with the idea of conclusive evidence. NFL, NHL and NBA have the same standard that there needs to be conclusive evidence to overturn. When you watch the other 3 leagues, 9 times out of 10 you can correctly guess the result of the review. With MLB, it's a real crapshoot. It is a joke.
If they want to have a different standard and say that their reviews will be called based on what the reviewing officials deems to be the correct call it would be one thing and I'd be fine with that. As it stands, their rules demand conclusive evidence to overturn yet their replay officials just make whatever call they want. It's unprofessional and stupid.
