You know when to watch them. You know where to watch them. Now it's time to figure out which Big Ten games are going to be the most important ones to watch in 2017.

The cutthroat East Division has plenty of high-powered matchups slated for the coming fall both in league play and in nonconference games earlier in the season. Let's take a look at the high-stakes battles that will have the most impact on the divisional race in the East, and largely on the college football landscape at large.

Ohio State vs. Penn State, Oct. 28

Let's start with the obvious. The defending conference champions visit the likely preseason No. 1 team in late October. If anyone is going to go toe-to-toe with Urban Meyer's high-powered Buckeyes, the Nittany Lions are a good bet. Penn State will head to the Horseshoe one week after another monster matchup against Michigan.

For the sake of keeping this list from getting too repetitive, let's lump the meetings between those three programs (Michigan plays Ohio State on the final Saturday of the season in a game that is, as usual, one of college football's biggest of the year) together. Whoever comes out of that round robin looking the best will more than likely have a strong case for a slot in the College Football Playoff. The stakes won't get any higher.

Ohio State vs. Oklahoma, Sept. 9

The second week of the season is loaded with intriguing and potentially season-shaping games. None will be a bigger draw than the top-10 rematch in Columbus. Ohio State beat the Sooners last season in Oklahoma with four passing touchdowns. The Buckeyes' tweaked passing attack for 2017 will get a chance to shine in prime time. If it succeeds, a victory would help the Big Ten's reputation as early-season narratives start to pick up steam and provide an early bullet point for Urban Meyer's playoff resume.

Penn State vs. Pittsburgh, Sept. 9

A few hours before kickoff in Columbus, the Nittany Lions will be looking for revenge against in-state rival Pitt. The first meeting between these two programs in 16 years provided some drama a year ago when Trace McSorley drove the Penn State offense down to the 30-yard line before he was intercepted in the final minutes of a 42-39 loss. After a season opener against Akron, the Saturday afternoon game in Happy Valley will give McSorley & Co. a chance to prove that they are picking up where they left off at the end of last season.

Michigan at Wisconsin, Nov. 18

If both teams hold their form throughout the regular season, this will be the top cross-divisional game of the year. The Badgers -- favorites in the West -- will get a chance to prove they're worthy competition for the East Division and pick up an eye-catching victory on a schedule that doesn't have many other opponents that rise above pedestrian. Michigan has to make this trip one week before hosting the rival Buckeyes. A win over Wisconsin would give the Wolverines a little more wiggle room in their championship hopes if they end up splitting with Penn State and Ohio State.
