Wisconsin's hot start in the 2021 recruiting class has gotten even hotter.

Following an unofficial visit to UW on Saturday, Top247 offensive tackle Riley Mahlman became the fifth commitment for head coach Paul Chryst in a class that now ranks sixth nationally.

Mahlman witnessed the Badgers pummel No. 11 Michigan, recording their second-largest victory in the history of the series in a 35-14 win.

"The atmosphere is always good there," Mahlman told Badger247. "In a big game, the way they played it, it brought out the best atmosphere. It was insane. It was crazy fun.

"I love how the whole city rallies around the team."

Mahlman also saw Wisconsin's offensive line pave the way for a 359-yard rushing performance, including 203 yards and two touchdowns from reigning Doak Walker Award winner Jonathan Taylor.

"They played smash-mouth football," Mahlman said.

Mahlman had early offers from Wisconsin, Minnesota, Iowa, Michigan State, Ohio State, Nebraska, Northwestern, and Iowa State.

The four-star offensive tackle was a high priority for offensive coordinator Joe Rudolph.

"I really like him," said Mahlman. "I've always had a good connection with him. I've known him for a while now and we've only gotten closer."

Notre Dame was also expressing interest in Mahlman this season.

The nation's No. 21 ranked offensive tackle is the second offensive lineman for the Badgers in 2021, joining JP Benzschawel (Grafton, Wis.).

"I really like Wisconsin," he said. "I think it's a really good fit for me."
