Wigan Warriors head coach Shaun Wane says he is still coming to terms with their heaviest loss to Castleford in the Super League era.
Tigers ran in seven tries in a 42-14 win as they thrashed last season's beaten Grand Finalists.
On top of defeat by Brisbane in the World Club Series, Wigan have won just one of their opening four league matches and sit seventh in the table.
"I have not recovered yet," 50-year-old Wane told BBC Radio Manchester.
"I think if we could have played Hull the day after that game the players would have jumped at it, rather than sitting in a video meeting with me.
"The sooner this Hull game [on Friday] can come then the players can look at redeeming themselves and get back to playing the way we know."
|Wigan's stuttering start|
|Widnes Vikings (A)||Drew 22-22|
|Huddersfield Giants (H)||Won 24-16|
|Brisbane Broncos (H)||Lost 14-12|
|Hull KR (A)||Lost 22-20|
|Castleford Tigers (A)||Lost 42-14|
After the game, Wane said he had "never coached a team that have been beaten in every department like that" - but expects his side to improve.
The former Wigan forward has been in charge at the DW Stadium since 2011, and guided the Warriors to a league and cup double in 2013.
"Over the years, even from Michael Maguire's years, we don't start really well," added Wane.
"We're not the biggest team, we're athletic. So we're coming up against bigger bodies but as a season moves on we normally finish quite strong, and that is a knock-on effect.
"They're easy lessons, we're just not learning them yet. That's my job, it stops with me.
"The players have to learn and we're working hard to make sure they get that."
