People that hate the Commanders more that the Eagles were typically adults back in the 1970s when George Allen was still a thing.
Ever since Gibbs left the first time and Dannyboy have taken over they have been a doormat. I find it hard to even take them seriously. Even when they win the division they are not very good and the RG3 flash in the pan followed quickly by a meltdown was comedy gold
OTOH, the Eagles from Buddy Ryan to McFlubb and Reid to Kelly and his gimmick not as innovative as they would have us believe offense to Dink Wentz have a lot to hate about them in more recent history.
Personally, I have come to hate the Giants and want them to lose no matter what. That primarily stems from my dislike of their owner and despot, John Mara, but there is plenty more vitriol to be had regarding Barber, Jacobs, Opie and I already miss that disgusted "WTH just happened" look from Coughlin after poor performances.
