The beautiful thing about the start of the MLB season is that every team begins the year in a tie for first place and with the chance to reach the playoffs.
Once the regular season gets underway, a much clearer picture of who the contenders are begins to emerge. There are always a large number of buyers at the MLB trade deadline and they are very willing to talk with the teams that are sellers.
A number of players will not finish the season in the same city that they began it with. These trade acquisitions will be brought in for playoff pushes and the teams that deal them will be looking for prospects or young players in return.
