Sunderland to bid for Bent

Sunderland might revive the career and place for Spurs forward Darren Bent.
Bent who had a forgettable first season for spurs after his move from relegated Charlton.He rarely got opportunity to start as he lost out to Robbie Keane and Berbatov.Last season also saw the departure of Jermaine Defoe to Portsmouth.
Daily Mail reports,Roy Keane is interested in signing Bent,who had only 6goals to his name for the concluded season.
This raised a question in my head,what is important?Playing week in week out or being in a team which can fulfill your dreams although not getting a place very often in the side..?
