Courtney Martinez | NCAA.com | September 3, 2015 College football: What to Watch Week 1 Share Attention all college football fans: It’s time to grab the remotes and huddle around the big screen TVs because the season is finally here. While there are plenty of games to fill your college football needs, the marquee match-up of the week is definitely No. 3 Alabama vs No. 20 Wisconsin. Check out what to expect in the game and what other storylines to follow throughout the opening weekend: Harbaugh's back: The hype surrounding Jim Harbaugh’s first season at Michigan has reached maximum heights this offseason. Now, it’s time to see what Harbaugh and the Wolverines can actually accomplish in his first game back. Utah players and coaches believe they’re ready to host Michigan and that they shouldn’t be overlooked in this game, especially after last year when the Utes defeated the Wolverines in Ann Arbor. Rematch in Blacksburg: The Hokies were the only blemish on the Buckeyes’ record during their 2014 championship season. It still hasn’t been announced as to who will start at quarterback for Ohio State, whether it’s J.T. Barrett or Cardale Jones. Plus the Buckeyes are without their star defender Joey Bosa. Regardless of these uncertainties, Frank Beamer and Virginia Tech will still have their work cut out for them against the Buckeyes. But if last year's game taught us anything, the Hokies will be prepared, especially since this year it's at home in Blacksburg. Return to Boise: Chris Petersen makes his anticipated return to Boise State when Washington travels over to the blue turf to take on the Broncos. The night will be a mixture of emotions for Petersen, who was Boise State's head coach for six seasons and recruited the majority of the Broncos' roster. It's been almost two years since he left for Washington but it will be interesting to see how the Boise State players and fans react to Petersen's return.
