I took a hit last week, guys. A big hit. I only got 50 percent of my picks right, with Virginia Tech, Georgia Tech, South Florida and Boston College all proving me wrong. My season total dropped to 71.7 percent (28 of 39 games). I’m trying to redeem myself this week, and it’s just getting tougher. This week, though, I’m counting on the Seminoles to show up, and I’ve got an upset brewing in Chapel Hill:

Florida State 24, Boston College 21 -- Those within the program seem convinced they’re better than they have played this season, and it’s not a question of talent or speed. It’s a matter of immaturity and costly mistakes. If the Noles have any pride, Bobby Bowden said this week, they’ll be ready for this one.

Clemson 31, Maryland 14 -- Until the Terps stop giving away points and moving backward with penalties, they don’t even give themselves a chance. There’s no question Clemson has more experience and talent on its roster, and these days, even home-field advantage isn’t so great for Maryland.

NC State 28, Wake Forest 24 -- Russell Wilson won’t be the difference in this game. The Pack’s defense will. Both Wilson and Riley Skinner will have their moments and put their team in position to win, but NC State’s defense is the best in the nation right now and it's ready to prove it against a conference opponent.

Virginia Tech 28, Duke 17 -- Duke quarterback Thaddeus Lewis will keep the Blue Devils in this game, and it will be closer than some will expect early on, but eventually, the Hokies will pull away. Virginia Tech was reminded how close this game was last year, and the Hokies aren’t going to let Duke ruin their chances at the national title.

Georgia Tech 31, Mississippi State 28 -- The Bulldogs are playing well, but it’s not a stretch to say LSU is overrated, and they didn’t beat the Tigers anyway. Georgia Tech’s offense turned the corner against North Carolina and is finally reaching its stride now.

Oklahoma 17, Miami 14 -- It doesn’t matter who is playing quarterback for the Sooners, because their defense will be too good for Jacory Harris and Mark Whipple to overcome. Miami’s offensive line will struggle against the Sooners’ defensive ends, just like it did against Jason Worilds last weekend.

Virginia 14, UNC 13 -- It’s time. The Cavaliers are due, and they’ve had more than a week to prepare. UNC is coming off a tough loss to Georgia Tech and won’t know what to expect from Al Groh and his offensive staff this week.
