Relegated Forest are favourites followed by last season's playoff losers, Tranmere and Hartlepool.
The Bees who are only mid ranked by the bookies however are predicted to have a positive season by Brentford fan Steve Smith on the BBC website.
From BBC.co.uk
Under the guidance of boss Martin Allen the Bees made the play-offs last season and with some good signings look set to build on it this season.
Dudley Campbell and Lloyd Owusu should end scoring problems and our solid defence, which kept 20 clean sheets last term, has been kept intact - a good season beckons.
Player to watch: Michael Turner
Optimistic Finish: First
Realistic Finish: Top six
League One winners: If not us, Nottingham Forest
The writers for BBC themselves said,
BBC Sport verdict: Brentford boss Martin Allen will hope to go one better than last season's play-off defeat after reshaping his squad during the summer with six arrivals and six departures.
Lloyd Owusu has returned to his old club and will join fellow new boy DJ Campbell up front while experienced duo Paul Brooker and Ricky Newman and Premiership youngsters Sam Tillen and Oli Skulason have also arrived.
Key man: Lloyd Owusu.
