The Cherries currently sit 21st in the League One table, and have won just one of their 13 games in all competitions, but the former England international goalkeeper says his team-mates are capable of outperforming any team in the division.
But James insists that the Cherries need to improve their defending from set plays.
He told the club's official website: "I think the team are good. None of the teams we have played against have been capable of doing what we are capable of doing when we get it right.
"In training we do some fantastic stuff. We just need to continue doing that, tighten up the set plays and all of a sudden we'll rise up the league.
"We have conceded four goals from set-plays in the last three games and it is something that needs to be worked out."
