Coaches never know what questions await them during a postgame press conference. Penn State coach Bill O’Brien knows this all too well following an emotional 24-21 overtime victory over Wisconsin on Senior Day at Beaver Stadium.

As BTN.com senior writer Tom Dienhart has done throughout the season, he offered his immediate thoughts to Saturday’s season finales. Get Dienhart’s Snap Reactions to Penn State’s emotional overtime win over Wisconsin and Michigan State’s victory at Minnesota in this post.

Sam Ficken hit a 37-yard field goal in overtime, and Wisconsin’s Kyle French attempt from 45 yards went wide left to seal Penn State’s 24-21 win Saturday in an emotional season finale in Happy Valley. The Nittany Lions (8-4, 6-2 Big Ten) could have ended it for good a play earlier, but linebacker Glenn Carson dropped a potential interception.

There’s no doubt who Penn State’s leader is. And we’ll see proof of it in Saturday afternoon’s season finale against Wisconsin at Beaver Stadium. The Nittany Lions are wearing No. 42 on the left side of their helmets in honor of injured senior Michael Mauti.

Penn State is honoring the 2012 football team on Senior Day by unveiling the year “2012″ on the Beaver Stadium facade where the years for previous national champions and memorable teams also live. Onwardstate.com has a little photo of the facade with a canvas hanging over the 2012. See it here.

Every week this season, BTN.com’s Brent Yarina (@BTNBrentYarina) and Tom Dienhart (@BTNTomDienhart) have offered their predictions for each Big Ten football game and provided polls for fans to pick their winners. We’re down to the final week of play, and BTN.com fans are in the lead.

This is the last week of the regular season. Rivalry trophies are on the line. (Hello, Old Oaken Bucket, Land of Lincoln Trophy, Heroes Trophy!) Bowl eligibility is up for grabs. A division title still must be decided. Here are the key questions for each team this week.

It’s Rivalry Week! Michigan at Ohio State. Indiana at Purdue. Illinois at Northwestern. Nebraska at Iowa. And a lot is on the line in the final regular-season week.
