It’s 60%. For guys with promises, in the future, don’t even remove them from the depth chart. If they’re too hurt to play, they don’t play. Then when they’re eligible to come back in, they come in, and you don’t worry about missing any promises. Unless you play FB/press, you don’t really use the 4th place on the depth chart, or shouldn’t need to anyway, and there’s no functional risk of re-injury, despite what some emails might tell you. Injuries are so rare in the first place, it would basically have to be like lightning hitting the same place twice in my understanding.
