This article is part of our CFB Waiver Wire series.
ACC
Cooper Helfet, TE, Duke
Helfet has done in the past two weeks what many tight ends wish they could do in a year. He's come out of nowhere to total 14 catches for 191 yards and a touchdown in his last two games, and he's a must-add in all formats until he cools off.
Sean Renfree, QB, Duke
Oh, how Renfree must regret his five-interception performance against Miami. Aside from that game, Renfree has been pretty good, and he's accounted for three touchdowns in each of his last two games. Although he's losing snaps to wildcat quarterback Brandon Connette, Renfree is still useful with the right matchup.
Big 12
James Sims, RB, Kansas
The Jayhawks are bad, but that didn't stop Sims from rushing for four touchdowns against the equally woeful Colorado Buffaloes. He's only rushed for 100 yards three times and has eight touchdowns on the season.
Josh Cooper, WR, Oklahoma State
Justin Blackmon is the big name as far as Cowboys wideouts go, but Cooper has been pretty good as well. He's scored in his last two games, and his spot as the team's No. 2 receiver seems safe.
Big East
Mark Harrison, WR, Rutgers
Harrison wasn't a big part of Rutgers' offense early in the season, but he's now scored a touchdown in four straight games. Clearly, he's a part of their offense now. The big wideout is making plays as defenses focus on Mohamed Sanu.

Dontavia Bogan, WR, South Florida
Bogan has had less than 66 yards in a game just twice this season, and on one of those occasions he scored a touchdown, one of his three on the season.
Big Ten
Roy Roundtree, WR, Michigan
Alas, you may be a week too late on Roundtree at this point. Is he going to catch nine passes for 246 yards and two touchdowns again? No, but he's had other really good games this season and is the top wide receiver in a potent offense.
Nathan Scheelhaase, QB, Illinois
Although he needs a good matchup to be useful for fantasy owners, Scheelhaase has shown in recent weeks that he's capable of going off in the right situation. Playing against Indiana, Purdue and Michigan, Scheelhaase has totaled 10 touchdowns while running for 264 yards.
Conference USA
Lance Lewis, WR, East Carolina
Dwayne Harris was the East Carolina wide receiver to own out of the gate, but suddenly Lewis' numbers are right in line with Harris' production. In fact, he has more receiving touchdowns (nine) than Harris (eight) at this point, though Harris has more yardage.
Alex Singleton, RB, Tulsa
Singleton's workload is shaky in Tulsa's spread offense, but he's the team's best running option near the goal line and a C-USA schedule means he'll have favorable matchups from here.
Independents
Gee Gee Greene, RB, Navy
He didn't get a chance to pad his numbers in Navy's 76-point onslaught against East Carolina, but he did score in that game and he scored in the three prior games as well. He's only an option in extremely deep leagues, but the Navy offense is rolling right now.
MAC
Jack Tomlinson, WR, Ball State
Tomlinson, a true freshman, didn't have a role in the Ball State offense until recently. However, in the last three weeks alone he's become Ball State's leading receiver, totaling 12 catches for 264 yards and five touchdowns in that span.
Chandler Harnish, QB, Northern Illinois
Harnish doesn't put up big yardage totals as a passer, but he's been a major fantasy asset this year due to his running ability and lack of turnovers. He's thrown just four interceptions on the year while running for 559 yards and four touchdowns.
MWC
JJ Di Luigi, RB, BYU
Di Luigi is the rare player who leads his team in both rushing and receiving yards. In addition to rushing for 681 yards and six touchdowns, he's caught 37 passes for 362 yards and a score.
Jonathan Warzeka, WR, Air Force
Warzeka only has 15 catches in Air Force's option offense, but he's becoming a legitimate fantasy option due to how often Air Force implements him in that rushing attack. In addition to his 348 yards and three touchdowns as a receiver, he's totaled 242 yards and three touchdowns on the ground. He even has another touchdown as a kickoff returner.
Pac-10
Chris Owusu, WR, Stanford
Owusu has had some issues staying on the field this season, but when he's played he's been good. Last week against a tough Arizona defense, he accumulated nine catches for 165 yards and a touchdown.
Jeff Tuel, QB, Washington State
Tuel has had a rough past two weeks, but the young passer should find more success as he takes on two of the Pac-10's worst defenses in Oregon State and Washington.
SEC
Tyler Bray, QB, Tennessee
The true freshman quarterback was given the starting spot over Matt Simms before Tennessee's game with Memphis, and he played as well as anyone could have hoped for. He threw for 325 yards and five touchdowns in the game, with almost all of the production coming in the first half. A weak Mississippi defense is up next for Bray.
Rueben Randle, WR, LSU
Randle started slowly, but he's scored twice in the last two weeks while gaining 198 yards. He may have been LSU's MVP against Alabama last week as he caught three passes for 125 yards and a touchdown.
Sun Belt
Aaron Spikes, RB, Lousiana-Lafayette
Spikes doesn't find much room to run in Lafayette's weak offense, as he's averaging just 3.1 yards per carry on the year. However, defenses haven't been able to stop Spikes the pass-catcher, as he has a touchdown catch in five of the past six games. That span includes games against BCS teams like Oklahoma State and Missisippi. Given that Spikes reportedly had scholarship offers from schools like TCU, Utah and Kansas State, it's not surprising that he's standing out in the Sun Belt.
Lester Jean, WR, Florida Atlantic
Jean started the season off well, trailed off a bit, and has now reemerged with three really good games. He's scored in all of his last three contests, and gained at least 79 yards in each, as well.
WAC
Kenny Turner, RB, New Mexico State
Turner only has two touchdowns on the season, but in recent weeks he's been more active both as a runner and receiver. That's allowed him to total 477 yards from scrimmage in the last four weeks.
Robbie Rouse, RB, Fresno State
In his last three games, Rouse has put up numbers to rival any running back's best three-game stretch. He's scored five touchdowns, and last week he rushed 43 times for 286 yards.
