Big Ten helmet stickers

Posted by ESPN.com's Adam Rittenberg

An exciting first weekend of Big Ten play is in the books. Penn State has established itself as the class of the conference, while Ohio State could be surging soon behind Beanie Wells and Terrelle Pryor. Michigan resurrected its season, while Northwestern and Michigan State continue to roll.

Helmet sticker time.

Penn State WR Derrick Williams -- The senior became the first Penn State player under coach Joe Paterno to rush for a touchdown, catch a touchdown pass and score on a special teams return in the same game. Williams made six catches for 75 yards and had a 94-yard kickoff return for a touchdown that put Penn State up 31-17 in the fourth quarter. Williams is averaging 36 yards per runback this season.

Michigan State RB Javon Ringer -- By this point, this guy deserves his own custom-designed helmet sticker. Ringer continued his feverish pace against Indiana, rushing for 198 yards and a touchdown on 44 carries. Ringer's 681 rushing yards in the last three games marks the best three-game stretch for a Spartans running back in team history.

Michigan's defense -- Too many contributors on this unit to pick just one. The Wolverines survived myriad miscues by the offense and performed in pressure situations in a historic comeback against No. 9 Wisconsin. From defensive end Brandon Graham (3 sacks, 2 forced fumbles) to nose tackle Terrance Taylor (8 tackles, fumble recovery) to linebacker John Thompson (INT return for touchdown), Michigan's defense stepped up big.
