Television True or False question about The Price is Right(Seasons 31-38)?

Rich Fields was the announcer until 2010, when he was replaced. I looked up Bob Barker, and they said he did the show until 2009, which is wrong, I thought he left in 2008. Then I looked up Drew Carey, and they had him starting the show in 2007, which I think is also wrong, because Bob and him can't overlap each other 2 years doing the show. I think Drew started in 2008. Rich Fields and Drew Carey only worked together for 2 years, from 2008 to 2010.
