R.J. Mickens wasted no time making a statement in his first taste of NFL action. The former Clemson safety had a day for the Los Angeles Chargers in their 27-13 preseason win over the New Orleans Saints, earning one of the top rookie grades from Pro Football Focus in Week 1.

Sixteen rookie quarterbacks made their NFL game debuts in the first week of preseason action over the weekend, and there was plenty of variance in the quality of their performances. There was also plenty of room for questions as they played differing amounts of time against differing levels of opposing defenses.

But now that there's legitimate NFL film to watch, grades are to be handed out, meaningless game or not. Yes, I was pumped to watch these prospects, whom I studied for months, on a professional field.
