Ian Rapoport had an interesting article that you should check out. Of particular note was a paragraph about Geno Smith's offseason activities:
After a trying rookie campaign that ended on the high of winning three out of the last four games, Smith took two weeks off. Then, he holed himself up at IMG Academy in Bradenton, Florida -- the place where he had trained for the 2013 NFL Scouting Combine. He shut out friends and media and fun. The training wasn't just physical, but mental, as well. According to a source close to Smith, the quarterback began studying film on the defensive coordinators the Jets will face this year, scouring tape for tendencies.
As we've said, Smith has had a fast start to training camp. He's looking a lot better than he did for most of last season. He's a known film junkie, so this isn't a huge surprise. Until the preseason games start, it's all hard to separate the wheat from the chaff, but right now, everything's coming up Geno.
