Dude did not want to mess up his shoulder anymore and did not want to go out there and look like an idiot; I don't blame him and lets be honest: People in the Baker cult or just simply don't like Watson, are going to find anything to nitpick him about.
Stefanski should have been knowledgable enough to know he had a rookie who I am sure was very nervous getting his first pro start and therefore needed to have a gameplan to benefit him; instead he did the exact opposite.
If fans blame DW for this loss, or call him a pussy or whatever, they're morons.
