Why do kids get re-assigned to different teams each year?
There are several reasons for this. (1) By starting with a clean slate each year, we reduce the likelihood that one team will dominate year after year, which would be unfair to the rest of the kids. (2) The quality of the managers and coaches varies, and it fairest to all kids if they experience different managers and coaches. It would be unfair for some to kids to experience only the best coaches while others might only experience only the least skilled coaches. (3) Basically, there are two ways to assign players to teams. You can either have a draft, where the managers choose players based on try-outs and other evaluations, or you can assign players to teams, to balance the competition as much as possible. In the Majors, where there is little turnover in managers, we use the draft method. In the Farm, where the managerial turnover is great, we use the second method, which means that we try to assign players so as to have balanced teams.
