Since I posted this, several other folks chimed in on Twitter. Holden Kushner from 106.7 The Fan estimated that the ratio was 70-30 cheers. Jack Kogod, a longtime Wizards and Redskins fan, put it at 60-40 boos. SB Nation's Mike PRada called it 50-50. Others suggested that
it was primarily Lakers fans who were booing McNabb, and that the booing was "not hardcore."
So if there's a silver lining it's that, at best, only half the home crowd booed McNabb.
Which, I suppose, is progress from his days in Philadelphia .
