Potter started at the club following his late October appointment amid concerns that the Tigers, who finished a disappointing 10th last season, would be well behind the rest of the competition by the start of the pre-season because of the coaching uncertainty.
But Potter said: ''The guys who have been here before had most of it planned anyway. We're on schedule in terms of where we wanted to be.''
Of his first day in charge of the players, he said: ''We had a field session and a weights session, and everything went to plan. It was my first day with the players, although I've met most of them.''
Hayden Knowles, a former strength and conditioning coach at Parramatta, has also joined the club as a physical performance manager.
Sheens' future, though, remains unresolved. The club, keen to avoid paying out its long-time coach, has maintained it wanted Sheens at the club in another capacity.
''There's no resolution at this point,'' Tigers chief executive Stephen Humphreys said. ''We're just allowing him whatever time he needs to think through his options.
''We're certainly not going to rush him with that. Tim deserves a bit of a break, so we've encouraged him to take some time off and let us know when he's ready.''
