Blazek had been the Badgers' offensive line coach for the last two seasons, but the group struggled with injuries and inconsistency that contributed to overall offensive struggles.
Left tackle Kevin Haywood suffered a season-ending injury last spring, leading the team to add Davis Heinzen in the transfer portal and start him at left tackle in Week 1. He lasted only one game before being benched and eventually moved to backup center, while right tackle Riley Mahlman flipped to the left tackle position.
The lineup also saw frequent changes at right tackle and right guard with young players rotating in with veterans.
The Badgers also saw two offensive line recruits decommit late in the process, though Blazek was able to successfully flip four-star Brady Bekkenhuis to Wisconsin from Boston College.

Mateos comes in as Fickell's third offensive line coach in four seasons, but he has past connections with offensive coordinator Jeff Grimes.
The two coached together during previous stops at Baylor and BYU.
Mateos' offensive lines at Arkansas had a strong reputation, and some Razorback fans were surprised when he was not retained on their staff.

He'll be under plenty of pressure to improve the Badgers' offensive line and get them back to the level of expectations that come with playing the position at Wisconsin.
His first challenge will be recruiting in the transfer portal, as the team looks to replace graduating center Jake Renfro and Mahlman. Left guard Joe Brunner is also undecided whether he will return to school or enter the NFL Draft.
