Well...no. He won the US Open in 2008 with a torn ACL and stress fractures in both legs and then quit that season to have surgery. In 2009 he started 17 tournament and won 6. He finished 6th at The Masters and the US Open, 2nd in the PGA Championship and 2nd in the Tour Championship. He also went 5-0 in the President Cup. Also finished 1sst on the money list (again) earning over $10 million.
Every other golfer on the Tour would love to be in that kind of "slump"...
I’m thinking of a little before 2008, around he got married, but I don’t follow golf that closely, so maybe I’m misinformed.
