I just recently came back to the game, and picked up two teams which I used to call my own.
And one more in a Roster only league.
Obviously, all 3 were unmanaged.
In only a brief time, the BOT management put those teams in heavy debt.
For this season and next ones, by giving out unreasonable contacts to old players.
Huge signing bonuses I will have to eat.
This is not a nice welcome to the game. Rather, it is a way to scare people off.
Other managers in my leagues will be glad to find in the waivers some good players available (on a cheap, bonus free, base salary). That's a plus for the league.
So, if the reason for screwing up bot teams is to provide fresh bodies to the waiver wire, mission accomplished.
As for rebuilding, the current system sucks big time
