The only source I have are my eyes and I watched every eagles game. There is a reason his YPC in his first 5 games was 2,9 and in the last 11 was 5,3 that are the games where the OLine was the worst at the start of the season. IMO he was never that great of a route runner he caught swing passes and alot of screens and check downs. Part 1 imo his passing production slipped was that screens did not work at all last year. Part 2 was the absence of DeSean Jackson. Teams were not scared of the Eagles deep, could play nearer to the LOS and key in McCoy. Finally I am not disputing that he was not his usual self and seemed to have lost a tiny step but saying he played awful is a stretch imo
