This was the toughest week to date. The hardest games to call were Clemson, Virginia Tech and Duke. Last week was my worst performance, going 5-3. Overall, I'm 27-9 heading into this week.
Here's what I've got for Week 5:
UPSET OF THE WEEK
Maryland 24, Clemson 21 -- Because of the injuries on their offensive line, the Tigers have to rely on Jacoby Ford, C.J. Spiller and Aaron Kelly. If Maryland can control those three players -- or keep them off the field by running the ball and controlling the clock -- they can win. Because of Clemson's injuries, the Terps should win the battle in the trenches, but their pass defense could bring them down.
Wake Forest 27, Navy 24 -- This could be a trap game for the Deacs. The Midshipmen have the nation's top rushing offense, but Wake has a veteran defense and Cool Hand Luke for their quarterback. Riley Skinner will be throwing into a pass defense that allows 176 yards per game.
Miami 31, North Carolina 10 -- Considering this is the season opener for UNC's backup quarterback tandem and it's a home game for the rapidly improving Hurricanes, the odds are stacked against the Tar Heels. Bill Young's defense will force UNC into turnovers and create a short field for OC Patrick Nix.
Duke 21, Virginia 20 -- The Cavaliers might have better athletes on their roster, but the Blue Devils have the better quarterback. What they probably don't have is much confidence against ACC opponents, but considering the sorry state of both programs, I'm going with the home team and the one with the better record.
Boston College 38, Rhode Island 3 -- The Eagles' defense should have no problem containing an FCS school that ranks 113th in rushing offense with 49 yards per game and Chris Crane should pass the test against a defense that has allowed 450 yards per game. URI has three straight losses.
Florida State 28, Colorado 10 -- The Buffaloes have to travel 1,488 miles just to be smothered by the Seminoles' defense in Jacksonville. The return of tight end Caz Piurowski will help the offensive line, and freshman running back Jermaine Thomas should help against a defense that held West Virginia to 3 of 13 third-down conversions.
South Florida 31, NC State 7 -- The Wolfpack will be without their top playmakers on both sides of the ball. Backup quarterback Harrison Beck has thrown three interceptions and two touchdowns this season while USF quarterback Matt Grothe is leading the Big East with 267 yards of total offense per game.
Virginia Tech 20, Nebraska 17 -- That's right, ANOTHER 20-17 win for the Hokies. Only because this is the Huskers' first true test of the season, and Virginia Tech has already proved it's a scrappy come-from-behind team. Plus, the Hokies have the veteran coaching staff.
OFF: Georgia Tech
