1-Now that Stubbs is gone, early on the Marty and Thom show turn their full attention to ripping on Jay Bruce. Bruce begins to hear boos at home, and the goobers on WLW turn on him as well, but most people just think they are saying Bruuuucccceeee. This eventually stops when people suddenly realize he's hitting his peak years and has stepped up his game.
Jay finishes with a 7ish WAR, depending on which system you prefer. Making him a MVP candidate, but he doesn't win because of being overshadowed on his own team by Votto and the eventual Cy Young winner. (see prediction 3)
2-Brandon Phillips begins to show signs of decline. He's still solid, and casual fans and most of the media don't notice, but the nerds like us realize he is just barely missing plays he would make in the past.
3-After this season everyone who predicted/wished Chapman would wind up back in the bullpen will not admit to ever saying that after he wins the Cy Young.
