The Republic of Ireland international is aiming for an immediate return to the Premier League and believes that relegation will help Rovers come back as a better team
Best was part of the Newcastle side that went straight up after just one year in the Championship, and he hopes to repeat that success at Ewood Park.
The 25-year-old, who moved to Rovers this summer from Newcastle, believes that winning promotion will make Rovers a stronger side in the future.
"With Newcastle, I think the season we had in the Championship built us and made us better in the Premier League," Best told Sky Sports.
"Now I want to do the same thing here. Sometimes you need that wake-up call to go down and build a good squad, go back up and work together."
The Republic of Ireland international is looking forward to linking up with other new signings Danny Murphy and Portuguese players Fabio Nunes and Nuno Gomes, who he revealed he has admired for some time.
"They're unbelievable signings," Best added. "I used to watch Nuno Gomes in the Euros and the World Cup for Portugal and to be playing with him now is unbelievable.
"Obviously Danny Murphy, with the clubs that he's played for - and as I know myself from playing against him last season - is a fantastic player."
The former Newcastle striker is also looking forward to working with manager Steve Kean again.
Best worked with the Scot at Coventry early in his career, and the forward has said with Kean he will be excited to start training with him again.
"He worked a lot with me at Coventry. He did extra bits with me that he didn't need to, any time I wanted to do shooting," said Best.
"His training gets the players going. You want to be part of it and that's a massive thing.
"I love getting up in the morning and looking forward to training and with Steve I'll definitely be doing that."
