The Georgia Tech junior regained his status as the nation's top wide receiver by overcoming a sore left leg to catch six passes for 165 yards and two touchdowns in the Yellow Jackets' 24-7 victory over Virginia.
That was good enough to move Johnson ahead of Southern Cal's Dwayne Jarrett in our power rankings, which measure the top players and coaches at each position.
This week's rankings feature a few other changes at the top.
Minnesota's Matt Spaeth replaced Oregon State's Joe Newton as the No. 1 tight end after catching five passes for 48 yards and a touchdown in the Golden Gophers' 27-21 loss to Purdue.
California cornerback Daymeion Hughes moved atop the list of defensive backs after scoring on an interception return for the second consecutive week in a 49-21 triumph over Arizona State. Hughes moved ahead of LSU safety LaRon Landry, who had held the No. 1 spot all season.
The Tigers still boasted at least one top-ranked player.
LSU defensive tackle Glenn Dorsey continued his rapid rise up the charts by replacing Texas defensive tackle Frank Okam as the No. 1 defensive lineman. Dorsey has emerged as the anchor of the Tigers' top-ranked scoring defense.
The ranking of a player and coach can fluctuate each week depending on how they fared the previous Saturday, but the power ratings measure their overall careers as well as their most recent performances.
For example, Spaeth moved to the top of our charts even though he wasn't the most productive tight end in his own game Saturday. That honor belonged to Purdue's Dustin Keller, who caught six passes for 120 yards. Keller made a big move up the list after that standout performance. But we're still not ready to say Keller's a better player than Spaeth, a four-year starter who earned first-team all-Big Ten honors last season.
By the end of the season, our power ratings should provide an accurate indicator of which players and coaches were the best at their respective positions.
