We're entering Week 4 of the season and this is when it starts to get really interesting. While looking around the league this week I noticed several offensive players who have stepped up their games and a couple of coordinators who are operating like sharks in a blood-filled pool. Here's a look at five things I noticed in the film room this week.
• I'm very impressed with the way J.T. O'Sullivan has played so far this season. He's handling this offense very well and despite a lack of game experience he's shown great maturity. He's reading the field very well and doing a fine job of finding the open man while also protecting the football.
