"It was cool to catch up with some of them," Pierschbacher said.
"Being a night game, it was a neat atmosphere," Pierschbacher said.
Saturday marked Pierschbacher's second Iowa game this season. He watched the Hawkeyes lose to Iowa State, 9-6, on Sept. 8.
"I know Iowa is a young team," he said. "Penn State is playing well, but I didn't think they were that good. I just think Iowa fell apart a little bit."
"I had some exposure to Oklahoma, so it was cool to finally get the offer," said Pierschbacher, who has twice visited Norman. "I'm not thinking too much about it right now, but when it comes time to make my decision, I will have that school in mind. It's nice to have the option of going there.
"It's a great program. They have great coaches. I feel comfortable there. I'll definitely look further into it."
Pierschbacher also boasts offers from Iowa, Iowa State, Boise State, Nebraska, Northern Iowa, Notre Dame and Wisconsin. He plans to visit Madison next weekend when the Badgers play host to Michigan State in a rematch of last year's Big Ten title game.
"I think they're interested," he said of the Crimson Tide. "I'm not sure if they're saying it to everyone, but they say I'm one of their top guys in '14. Hopefully after the season is over and I go visit them, I'll have my highlight tape done. Hopefully they're impressed and will offer. We'll see."
As his junior season comes to a close, Pierschbacher is preparing for the next step in his recruitment.
"I'm going to wait and see who offers after the season and get a list together of where I want to go," he said. "I'll take those visits and then maybe start narrowing it down a little bit. Once it seems like the scholarship offers are coming to a stop, I'll narrow it down."
Cedar Falls opens the playoffs Wednesday against Davenport Central in the UNI-Dome.
"I like where we're at as far as bracket wise," Pierschbacher said. "We got a pretty good draw but it's one game at a time."
