Putting aside his well-earned reputation as a “conservative” jackass, if Rush Limbaugh hadn’t said what he said about Donovan McNabb, McNabb would have been benched by now. All the commentators cutting him slack by blaming his lack of a supporting cast seem to be making an exception to the accepted rule of thumb that gives the QB the bulk of the credit AND the blame. Andy Reid needs to bite the bullet and bench McNabb before the Eagles’ season gets away from them. Period.
