The long-standing notion in baseball is that a general manager hates to trade one of "his guys." "His guys" are often defined as the following: the big-dollar free agent for whom ownership begrudgingly gave approval; the young player obtained in a trade for the aging All-Star; the first-round draft choice who received a massive signing bonus. This offseason, however, we may see unprecedented turnover on rosters because of the many front office changes. Six franchises have changed general managers since the end of the season: the Orioles, Red Sox, Twins, Angels, Cubs and Padres. In addition, the Astros have a new owner who hasn't said whether Ed Wade will stay on the job.
