Just a minor suggestion: Training bonus (say 10%)
It's a preset from BB, a season consists of approx 14 weeks, so similar to TV games stuff, there will be 3 weeks to have training bonus. The following is just an example:
26 Feb 2016: Training Bonus for 1 on 1 training in this week
18 Mar 2016: Training Bonus for Reb training in this week
22 Apr 2016: Training Bonus for OD training in this week
This would give the managers to choose the bonus or not. Maybe managers give up training bonus as there are 3 tough games in that week. Three different types of training will be randomly selected by BB server, one is outside skill (OD, JR, PA, HN), one is inside skill (IS, ID, Reb, SB) and another one is general (JS, DR, Stamina, FT).
