The 20-year-old Miller endured a difficult start to his Super League career as Hull suffered a shock 30-28 defeat at Castleford last Friday, less than a week after arriving from Sydney to plug the gap created by the departure of fellow Australian Brett Seymour.
"I know about Jacob," Wakefield assistant coach Webster said. "I saw him play in Australia and my brother (Andrew) coached him at Wests Tigers. It's hard for a kid to come into a new team in that position and stamp his authority really early, but what I saw were good foundations for what will probably be a good career for him at Hull FC."
He added: "He's got a good head on some young shoulders and with the squad they've got, especially their back-rowers, I think he's going to go well for them."
Hull are boosted by the return of England forwards Gareth Ellis and Danny Tickle and winger Tom Briscoe as they look to halt a two-match running run and Webster, whose Wildcats side have already lost twice to the Black and Whites this season, knows how difficult they are to beat at the KC Stadium.
"Their home form is outstanding," he said. "I think you can count on the fingers of one hand how many games they've lost at home over the last two years.
"And, other than Richard Horne, I think they've a fully-fit 25-man squad. Danny Tickle is back and we're expecting Ellis and Tom Briscoe to play as well.
"But we'd back our side to go to any ground at the moment and play well. If we can put our best foot forward, I think we'll be in with a chance."
Wakefield have run into form with back-to-back wins over Salford and London to rekindle their play-off hopes and they are boosted by the return from suspension of lively hooker Paul Aiton.
"Paul's been good for us," Webster said. "He's probably our most consistent player. He adds a bit of steel to our middle, he's a real tough competititor. We're looking forward to Paul coming back."
