Bradford Bulls coach Francis Cummins was frustrated with his team's forward play despite victory over Castleford.
Brett Kearney's hat-trick helped Bradford to a 38-12 win at the Provident Stadium after the visitors had been reduced to 11 men.
Castleford once again showed the resilience that earned them a shock 14-12 victory over champions Leeds the previous week, but eventually ran out of steam when backs Justin Carney and Gareth Ellis were sin-binned in the closing stages.
Bradford enjoyed plenty of possession but failed to capitalise and Cummins said: "We were a bit edgy when we get down there near the line. We're trying to score a try all the time when if we ask a few questions, we'll get there.
"We just need a little bit more direction at times. I liked some of the stuff - we were skilful and made a couple of good off-loads but our structure just went away from us at times."
Cummings was full of compliments for Kearney, who has now scored in all three matches this season, taking his tally to five with the hat-trick.
"He's a quality player - he's huge," added the Bulls coach. "He catches the ball well and runs with it and defends everywhere."
Castleford coach Ian Millward was unhappy with some of the officials' decisions, having also lost on-loan from Warrington debutant Gareth O'Brien for most of the game after a controversial clash with Nick Scruton early on.
A cautious Millward said: "I'll have a look at everything but I was confused. But I'm not going to sit here and pinpoint the ones (decisions) I was concerned with."
On his side's display he said: "We showed some backbone and some spine.
"We continually repelled the opposition when we were pinned on our own line
through repeat sets which is pleasing."
