Wentz didn't exactly tear up the defense on the first day the Eagles could conduct 11-on-11 team drills this offseason. He threw almost as many incompletions as he did successful passes, he was "sacked" several times, and one of his deep throws was intercepted. But it's difficult to watch him throw, or roll out, or connect with new receiver Alshon Jeffery and not at least understand why the Eagles are optimistic about the coming season.
