Cook not thrilled with first start

The Vikings can only hope QB Tarvaris Jackson does better in his first start than RT Ryan Cook.
Cook committed two false starts, and he said he also missed two assignments.
Asked to describe his play, Cook said, "Mediocre, at best."
Cook said there was no excuse for his false starts.
"If you have those type of things, you don't help yourself win," Cook said.
Vikings coach Brad Childress indicated Cook may not necessarily start again.
"You know those guys have still continued to mix that thing up, he and (Mike Rosenthal)," Childress said. "But you know those things kind of come through as we are out here and how they prepare and those kind of things."
Cook, though, isn't rattled by his poor start. He said he will continue to hold himself to a higher standard.
"I take that as a learning experience," he said.
