If Chicago Bears general manager Ryan Pace wants to get serious about Mitchell Trubisky becoming the next Carson Wentz, Philadelphia Eagles quarterbacks coach John DeFilippo needs to be on the list of candidates to replace John Fox if the Bears head coach is let go after the season. The 39-year-old DeFilippo isn’t a conventional choice since Frank Reich holds the title of offensive coordinator in Philadelphia, but talk to people around the Eagles organization on a daily basis, and they say no one has been more instrumental in Wentz’s development than DeFilippo, who’s also worked for the Browns, Raiders, Jets and Giants. At the very least, DeFilippo should be interviewed for the Bears’ top job. The results speak for themselves. In just his second season, Wentz, who like Trubisky went second overall in the draft, is a legitimate league MVP candidate. Wentz’s three touchdown passes in Philadelphia’s 31-3 victory over the Bears on Sunday give him 28 on the year to just five interceptions. Wentz truly has the “it” factor that Fox (12-31 in Chicago) referenced a while back. But the Eagles also set Wentz up for success -- from the offensive system, the concepts, the coaching staff and the supporting cast. In a copycat league, the Bears must do the same for Trubisky.
