Adrian Lam on 'small steps' and Dom Manfredi's try-scoring return for Wigan Warriors
Winger Dom Manfredi marked his comeback from a 10-month lay-off with a second-half try as the Warriors claimed a 26-12 win.
"I was really pleased and we defended well again," said Lam, who saw his side climb to second in the table after a third win from four matches.
"That's four weeks in a row we've scored two tries against us - and they were both against the run of play, so I'm really happy.
"We've taken small steps, there were four or five opportunities we could have capitalised on as well, but we looked better movement and shape.
"When that comes together there's going to be a big score and I'm looking forward to that happening."
Manfredi's return from a third major knee injury in four years was one of the main positives.
"Dom's respected highly by his peers, they love him," said Lam, who reported no fresh injuries. "He wasn't quite mentally right last week, he wanted to play reserves - and that will do him the world of good.
"His carries are some of the strongest not just in Super League but in the world I reckon."
Bevan French scored Wigan's only try in the first-half. He presented FC their only touchdown before the break - but that error wasn't enough to distract from another eye-catching display.
Hull FC were solid but they lacked a threat and coach Lee Radford said: "In the second-half Wigan came out and did a tidy job, and slowly ground us down.
"Some of our plays were painful. Josh Griffin was head and shoulders our best player."
Wigan are second in the ladder, level on points with leaders Huddersfield - setting up an intriguing top of the table clash in West Yorkshire next Sunday.
