Chip Kelly says Philadelphia Eagles only made four changes on offense, which isn't true

The Philadelphia Eagles made a lot of changes to their team this offseason, especially on offense. They traded away their starting quarterback (Nick Foles) and starting running back (LeSean McCoy), released both starting guards (Todd Herremans and Evan Mathis), and let their most productive wide receiver (Jeremy Maclin) walk in free agency after making an effort to re-sign him. Despite this, Kelly thinks the Eagles' personnel turnover is overblown. Speaking to Tampa Bay beat writers in a conference call prior to practice on Wednesday, Kelly said the following:

Eagles' Chip Kelly says "we only made four changes on offense." Said idea of wholesale offseason change is "overblown."

"Four changes" just doesn't add up. Five moves have already been listed above. In conjunction with those departures, the Eagles added the following players as significant contributors on offense: Sam Bradford, DeMarco Murray, Ryan Mathews, Nelson Agholor, and Miles Austin. The Eagles also are relying on some of their home-grown players more often than they have in the past; Josh Huff and Zach Ertz are playing more than ever before. Former backup offensive linemen such as Allen Barbre and Andrew Gardner were thrust into starting roles.

And the number of changes isn't even the whole point. It's also about the impact of the players. The Eagles made significant changes at some of the most significant offensive positions. Philadelphia is the first team since the 2008 Bears to move on from their top passer, rusher, and receiver in the same offseason.

Kelly wasn't necessarily wrong to move on from the players. Continuity for continuity's sake isn't good. But his replacements haven't been much better. Philadelphia's offense ranks 23rd overall by Football Outsiders. They rank 25th in yards per play and 23rd in points per play. They're tied for 8th in giveaways.

So, no, the offensive turnover isn't overblown. It's an issue that has contributed to this 4-5 team's mediocrity this season.
