The Facts: Eagles WRs coach Mike Groh believes Jeffery had his best offseason since perhaps 2013, when Jeffery burst onto the scene and set career highs in catches (89) and yards (1,421) while finding the end zone seven times. "He and I have a history together. ... I understand the way that he works and goes about his business," Groh said. "I think the spring that he's had is as good as he's had since maybe 2013."

Diehards Line: Groh was the Bears' receivers coach for three seasons (2013-15), which proved to be the most productive years of Jeffery's career to date. During their first two years together in Chicago, Jeffery -- working opposite Brandon Marshall -- racked up 174 catches, over 2,500 yards and 17 TDs. His lone Pro Bowl appearance came in the '13 season that Groh referenced. Marshall made it that year as well. With Jeffery currently healthy and back together with his old coach, the hope is that he'll return to form in '17.
