When Odell Beckham Jr. exited the 2017 season after just four games due to a broken ankle, the already suspect New York Giants offense became a meandering operation stumbling aimlessly through the gridiron jungle.With OBJ appearing on pace to return fully healthy, the Giants should have their field-tilting game-changer back. Eli Manning, speaking at a football camp at Kean University, said Beckham looked like his old self again during last month’s workouts.”Odell looked healthy,” Manning said, via ESPN’s Jordan Raanan. “He was running routes full speed, making cuts and seemed to be his old self. So I’m excited about that and that he can go out there and run all the routes.”So, excited to get him back going once training camp hits up. And getting on the same page, there are always new routes and new tweaks to the offense. But I know he’s been working hard and is going to have a big year.”Getting Beckham back fully healthy is the most important piece to boosting Manning’s final years with Big Blue. While the additions of Saquon Barkley to the backfield, Nate Solder and Will Hernandez to the offensive line, and the growth of wideout Sterling Shepard and tight end Evan Engram are all important boosters, no player affects defenses the way OBJ can. His return makes everything on the field easier.The biggest issue Manning sees Beckham needing to get used to when training camp opens later this month is wearing a shirt.
