Campbell, on-loan at Spurs from Manchester United, helped Hull win promotion last season and Brown said: "Fraizer's loan spell was one of the main reasons why we're in the Premier League.
"But Fraizer's goals are certainly part and parcel of us being promoted.
"It was a team effort last season, no doubt about it but the lad came in and he was bright, freshfaced and played the game in a way that reminded me of myself to a certain extent.
"You could kick me all day but I'd just get back and keep running. I'd probably even laugh at people doing it.
"Campbell's pace is one of the biggest assets that he has and he's a genuinely great kid."
