That would probably depend significantly on the leadership and culture Epley was working under.
A prevailing thought/rumor right now is that accountability and S&C did not go hand in hand under the previous staff. Some rumors suggest it was common for certain players to not show up for S&C or morning workouts and they would get away with it. If this is true, it would be tough to implement effective workouts and hold players accountable without complete buy in and repercussions for choosing not to do the work.
