The boos started on Donovan McNabb's first throw, grew louder after his second pass was nearly intercepted, and reached a fever pitch when his third attempt was almost picked off, too.
Vikings fans were just getting started. The catcalls intensified with each errant throw.
"I can't worry about that," McNabb said.
Vikings coach Leslie Frazier acted oblivious to the obvious.
"Never heard it," he said. "All I heard was cheers."
Yep, it was a real hoot.
Oh, by the way. The Vikings led 28-0 after one quarter en route to a 34-10 victory against the Arizona Cardinals that -- judging by the "cheers" from the Metrodome crowd -- felt like a 24-point loss any time McNabb dropped back to pass.
It was a weird atmosphere. It's almost as if the Vikings won in spite of McNabb, thanks to Adrian Peterson's running, their defense's dominance and a horrendous performance by the Cardinals offense and quarterback Kevin Kolb in particular.
