Castleford director of rugby Chris Chester told BBC Radio Leeds:
“We did well in that first 40 minutes and were unlucky not to get that try just before half-time.
“I’m really disappointed with the second half. That’s been us for the last 20-odd weeks.
“We showed in parts that we can play some good stuff and are a good team. But with a little bit of adversity and a bounce of a ball going against us, we seem to just crumble.
“It’s been a tough week for the guys and I know they’re trying. There were spells when we looked a better team in that first 10–15 minutes, but we’re just not doing it consistently well enough for 80 minutes.”
Hull KR head coach Willie Peters told BBC Radio Humberside:
“I’m really happy with the second half. It was a very professional performance.
“Getting that zero is something we pride ourselves in. We haven’t done that too often this year, so I’m really pleased with that.
“I want to pay tribute to our captain [Elliot Minchella]. He’s had to do it the hard way and that’s what has made him the player he is.
“Tonight was a really positive performance. [Over] these last three games, he’s back to how I know he can play.”
