It's always fun looking back on what we thought in the preseason, and today, we'll take another look.
Here's who made the postseason team.
DL: Jackson Jeffcoat, Texas
Jeffcoat was off to a solid start with 9.5 tackles for loss and four sacks with a pair of forced fumbles in his first six games, but a torn pectoral muscle ended his season early and he didn't make the postseason team.
DL: Stansly Maponga, TCU
Maponga was TCU's lone representative on the preseason team, but he didn't quite live up to expectations, and was overshadowed by teammate Devonte Fields. Maponga made just six tackles for loss and 3.5 sacks, neither of which ranked in the top 10 of the Big 12. He did force two fumbles but didn't make the postseason team.
DL: Alex Okafor, Texas
Okafor was solid this season, and wasn't far off from being the Big 12's Defensive Player of the Year. He was third in the league with eight sacks and sixth in the league with 11.5 tackles for loss. He also forced two fumbles and made the postseason team.
DL: Meshak Williams, Kansas State
I took some flack for including Williams on my preseason team, but I'll have the last laugh here. I loved his relentless motor and underrated technique and use of hands in 2011. This year, it paid off with a Big 12 Defensive Lineman of the Year trophy after leading the league with 9.5 sacks and finishing third with 13.5 tackles for loss. He obviously made the postseason team.
LB: A.J. Klein, Iowa State
Klein returned as the league's Defensive Player of the Year and had a really solid year with 98 tackles and an interception returned 87 yards for a score. He also had 2.5 tackles for loss and made the postseason team.
LB: Arthur Brown, Kansas State
Brown didn't have a huge statistical year but he held together a solid K-State defense and flew around all season, even playing through a painful ankle injury. He won Big 12 Defensive Player of the Year honors for his efforts and made 91 tackles, six tackles for loss and intercepted two passes, returning one for a score. He obviously made the postseason team.
LB: Jake Knott, Iowa State
Knott was having a great year with 79 tackles and two interceptions through eight games, as well as five pass breakups and two forced fumbles. He suffered a shoulder injury that required surgery, though, and played one last game, going out on top with a win over Baylor. Despite the injury, I still placed him on the postseason team.
CB: Carrington Byndom, Texas
Byndom was my pick as the league's top corner this year, but he was part of Texas' defensive struggles and got surpassed by some better players. The Longhorns pass D ranked third in the league, but Byndom was 21st in pass breakups, though he did have three interceptions and two blocked kicks.
CB: Brodrick Brown, Oklahoma State
Brown and teammate Justin Gilbert were two of the bigger disappointments across the league this year. The duo combined for 10 picks a year ago. Neither had one this year, and OSU ranked seventh in the league in pass defense. He was surpassed by better performances on this year's team by Aaron Colvin and Jason Verrett.
S: Kenny Vaccaro, Texas
Vaccaro had a solid year with 93 tackles, two interceptions 3.5 TFLs and two forced fumbles, but I gave the narrow nod to K-State's Ty Zimmerman for the second safety spot on the postseason team.
S: Tony Jefferson, Oklahoma
Jefferson was one of the league's best defenders this year and finished second in the league with 113 stops. He picked off two passes and broke up three more. He made the postseason team.
