SEATTLE - You sat here at CenturyLink Field on Sunday and watched with a perverse combination of curiosity and horror as the Eagles lost to the Seahawks, 26-15, and you wondered: Who was the last Philadelphia athlete to be as mentally lost as Nelson Agholor is? Ilya Bryzgalov? Domonic Brown? Nnamdi Asomugha? Did they sink this low? When Joe Cowley forgot how to throw strikes for the 1987 Phillies, was it as excruciating to sit through his four appearances then as it is to see Agholor make the kinds of fundamental mistakes that a Pop Warner coach couldn't forgive?
