If you are not concerned with winning at all costs, in the future you can play patient offense. Your trainee will get a lot less touches in that offense reducing the likelihood of injury. In the meantime train free throws or stamina so your trainee benefits while being injured.
Agree with this. If your 5/5 C is the absolute sole focus of your training program, you could view this as an opportunity to train stamina/FT. When your star trainee is fit it's a harder decision to make as you always want to be improving on those primaries, but higher stamina in particular will do no harm at all.
