Sicario2 - Tier 1
I agree.
For me it's binary, and appears likewise for football managers. Either you can participate in training and play at your full capacity in spite of your injury, or the injury limits you from participating. In the former case, the players will almost always play, in the latter they won't, until they can participate fully in training.
and the barometer for whether a players plays on matchday or not is whether they participate in the training session before the game, and thus be declared fit.
