With 2 trainees, you can get them both 48+ (48.0 or more minutes).
You will be in the relegation series, so next week you will have 3 games:
25/2 last league game
28/2 relegation game
2/3 scrimmage
then the following week you may have 3 or 2 games depending on the relegation series:
4/3 relegation game
7/3 potential relegation tiebreaker*
9/3 scrimmage
If you have the relegation tiebreaker you will pay salary for an extra week, but you will have an extra game. For you it shouldn't matter much since your salary is very low anyway.
The following training week goes across seasons:
11/3 automatic scrimmage (you don't need to do anything it will be automatically set up against Forever21eternals)
16/3 scrimmage (as usual) <-this game is in s38 your trainees will be 1 year older
Hope this helps
