This is important because, as you may have heard, Manning had ankle surgery in early April and was supposed to be cleared to start running by around now but wasn't expected to be practicing on the field with his receivers and the rest of his offensive teammates as they learn the new offense being installed by Tom Coughlin and new coordinator Ben McAdoo. The fact that Manning is on the field, taking snaps and throwing passes has to be considered an encouraging sign for the Giants.
Manning values practice time as much as anyone in the league and didn't want to miss any, let alone an entire spring's worth. Coughlin said on draft weekend that Manning had already been out on the field some and that he would be allowed to practice if he had no setbacks, and that appears to be what's happening. The Giants will surely monitor Manning to make sure he doesn't put himself at risk of further injury by practicing. But we all know that Manning hasn't missed a game since becoming the Giants' starting quarterback in 2004 and that he's a quick healer. So it now has to be considered possible that he has something close to a full offseason to prepare for 2014, and that he'll be a full go for training camp when it starts in late July.
