what if they went to a "challenge" system with reviews but each team were given one challenge PER WEEK? Yeah, it might be a bit of paperwork nightmare keeping track of who has their challenge and who doesn't, but think about it, if you've got a reviewable play occurring during a game on Monday, as the manager you have have to decide if it's big enough of a situation to blow your challenge or save it for a possible "bigger" game later in the week. Otherwise, I'm all for review on close plays at the bag/plate, trap/catch in the outfield and fair/foul calls on balls hit down the lines. But, yeah, use a booth review like the Big Ten does to keep the game moving. Balls/strikes, however, should never be reviewable.
