Victorious coach Peter Gentle described his Hull side as "a rabble" after they squeaked home against Rovers in the Magic Weekend derby.
Hull trailed 16-6 going into the final 10 minutes, but three tries in eight minutes turned the game on its head.
"We played for about 10 minutes today and put our worst 80 together for some weeks. We were a rabble," said Gentle.
"The occasion got the better of us but credit to our guys, we kept the scoreboard within reach and thought that if we got one try we could get two.
"I told the players they should enjoy the win but they have a lot of work to do on Monday. We were a mile away from where we should be but the rugby league gods looked after us."
Gentle was philosophical about the match-winning try, despite fury in the Rovers ranks after replays showed Chris Green was off-side.
The RFL admitted this evening that video referee Steve Ganson had made the wrong decision.
Speaking before the RFL statement, Gentle said: "It sort of squares it up for last year.
"You would need to talk to the referees. I'm not sure about the ruling, but we will take it."
