Did Donovan mcnabb really get traded to the redskins?

No, Donovan McNabb is not the only quarterback to go from the Philadelphia Eagles to the Washington Redskins. In recent years, the Redskins have acquired several players from the Eagles, including quarterbacks:

• Sam Bradford (2015)
• Nick Foles (2017)
• Mark Sanchez (2014)

However, most of these players only spent one season with the Redskins, while McNabb's tenure with the team spanned from 2010 to 2013.
