It's that time again, time to dole out helmet stickers for Week 2 in the SEC. There weren't an overload of marquee games in the SEC this week, but there were a few terrific performances. Here are this week's winners:

Georgia tailback Knowshon Moreno: What leg injury? Moreno looked better than ever in Georgia's 56-17 thrashing of Central Michigan. He rushed for 168 yards on 19 carries and scored three touchdowns for the second straight week. One of those was a 52-yard gem where Moreno showcased his speed, vision and power all in one vapor trail to the end zone.

Alabama special teams: Without the kicking game, Alabama would have been in real trouble. The Crimson Tide scored their first two touchdowns on special teams, an 87-yard punt return by Javier Arenas and a blocked punt and 13-yard return for a touchdown by Chris Rogers. Arenas' return was as pretty as you'll ever see. He broke at least four tackles and then turned on the jets, as Alabama held off Tulane, 20-6.

Vanderbilt coach Bobby Johnson: Hey, let's give Johnson his long overdue props. The guy can coach. Vanderbilt knocked off South Carolina on Thursday night for its first home win over a nationally ranked team since 1992. More importantly, the Commodores are 2-0. Johnson is getting better players into the program, and his teams are tough, disciplined and always prepared. None of his high-paid coaching counterparts in the SEC could have done any better job than he's done at Vanderbilt, and he's done it with class.

Arkansas tight end D.J. Williams: Talk about a one-man show. Williams showed why he's one of the best pass-catching tight ends in college football in Arkansas' 28-27 escape against Louisiana-Monroe. He had five catches for 124 yards, including a pair of touchdowns. His 8-yard touchdown catch with 1:22 to play won it for the Hogs after his 76-yard catch and run earlier in the fourth quarter set up a short touchdown run to pull Arkansas within 27-14.
