Size Doesn't Matter

Some people I know have started to ask if (or convince me) Tim Lincecum is done?
"His velocity is down."
"He lost too much weight."
"His mechanics aren't built for the long run."
I would agree, except that these were the same arguments last April (except the weight issue was then that he had gained too much).

The Atlanta game brought scrutiny with Lincecum. In 2010 it was the month of August that had everyone up in arms over Timmy;

By far his worst numbers in his career for a month until now (and we know how that ended, in a world series victory and dominant play-off performance by Timmy). So, is he done? No, not by any stretch of the imagination. Am I worried? Yes. Is it because of his numbers? No, not necessarily. It's more because of what I saw in the first inning of the Phillies game; His composure. Unlike most critics who believe Timmy's struggles are physical, I believe that they are mental, like most baseball players struggles are. When Dave Righetti was on the mound to talk to Timmy in the first inning you could see a very concerned, almost scared or bewildered, Tim Lincecum. He looked vulnerable. That is what worries me. The physical tools are there and they are coming along as they always do, but Timmy needs to get his mind right. He needs to buck up, light a fire, do something fierce. If he can't regain some type of edge then we may be in for a long season.
