Wisconsin freshman earns Badgers' highest honors on All-Big Ten defense

In this story:
The Wisconsin Badgers only had one player make it onto any of the first, second or third-team All-Big Ten teams, and it was a true freshman who barely played in the first half of the season.
The conference announced its defensive honorees for the 2025 season on Wednesday, and linebacker Mason Posa made it on the third-team all-conference.

No other Badgers defensive player was present on the first, second or third teams, and it would be surprising to see any Wisconsin offensive players earn all-conference honors given their massive struggles this season.
Luke Fickell's defense did have four other players make it on the honorable mention defensive team: outside linebackers Darryl Peterson and Mason Reiger, inside linebacker Christian Alliegro and cornerback Ricardo Hallman.

Posa emerged as a breakout freshman quickly after he started earning extended playing time halfway through the season.
His first start was Week 9 at Oregon, though his role started to grow in Weeks 7 and 8 against Iowa and Ohio State.
Had he played more from the very beginning, he would have had a strong case to be first or second-team All-Big Ten this year.
Despite his late start, he still finished as PFF's highest-graded linebacker in the conference and seventh highest-graded linebacker in the country.
Posa looked like a future star in the making with a well-rounded skillset as a run stuffer and blitzer up the middle.

He could stand to get more comfortable dropping back in pass coverage, but for a true freshman thrown out there against some of the top offenses in the country, he held his own.
He'll be one of the most important players for Fickell and his staff to retain and not let anywhere near the transfer portal this winter. Posa is the kind of player they can build a defense around for the next three years.
