It's not easy being a rookie in the NFL. The playbooks are HUGE, the opponents are HUGER, and everyone is really, really fast. Even the fat guys!
But this is the time of year that a lot of rookies start to settle in. Obviously, Robert Griffin III is off to a fast start. But from here on in, I expect Andre Luck to be just as good. Even Ryan Tannehill is showing signs of being a very good quarterback as a rookie.
And look out for Trent Richardson. The Browns rookie got off to a bit of a slow start because of some knee problems, but it looks like he's 100% and ready to start dominating. It's never a good idea to rely on rookies early on, but right about now is when you'll see the young guys start to break out.
