I'm very sorry to hear his knees are bothering him. I'm glad to hear that he's "putting SA behind him" and just moving ahead with training and plans for TEB. I really like Tim, and it's been heartbreaking over the last couple years to see him struggle so much with physical problems that led to losing the jumps, etc.
I was also a little to see him be the second US man this season to gripe about COP. Especially the nature of his gripe related to point values for quads v. 3/3's. Considering he hasn't been able to land much of either lately....it just seemed a bit whiney to me. But that's probably nit-picking, as our friend Dick would say.
ETA: We'll have to invite Tim to our Whine and Cheese party during Nationals!
