Ohio State is back in the Final Four for the first since 2007, when it advanced to the national championship game and lost to Florida. The 2011-12 journey was an up-and-down one. Along the way, the Buckeyes were ranked as high as No. 2 and also struggled through a 2-3 funk in February. But they were at their best when it mattered most, winning eight of their last nine en route to making the Final Four. Now that Ohio State is off to New Orleans for the national semis,'s Brent Yarina takes a look back at the key moments and plays that have the Buckeyes in this position.

Nov. 29: In the Big Ten/ACC Challenge, then-No. 3 Duke visited Value City Arena, and the Buckeyes won so easily it prompted this quote from Coach K: "Sometimes you just get your butt kicked." Indeed. (BOX | AP RECAP)

Dec. 31: It came in Ohio State's first Big Ten loss of the season, but freshman Sam Thompson threw down one of the best dunks of the 2011-12 season. He went on to have a few other similar jaw-dropping slams, including a similar one in the Elite Eight against Syracuse.

Jan. 15: In a rematch against Indiana, Lenzelle Smith Jr. introduced himself to the nation, with a career-high 28 points on 10-of-12 from the field. Smith, who had scored in double digits just once in his career, was averaging 5.1 points entering the contest. (BOX | AP RECAP)

Jan. 29: It's that Lenzelle Smith Jr. guy again. After scoring a total of two points in the previous two games, Smith scored 17 points and grabbed a career-high 12 rebounds, including eight on the offensive end, to lift Ohio State past rival Michigan. (BOX | AP RECAP)
