"We were really impressed with the facilities," said Blomstrom, who also liked the rural setting of the campus. "Oklahoma State's athletic facilities are the best I've seen. They put a lot of money into it.
"You can tell their trainers take good care of you as a player. You get to sit down and eat every night with the team - away from the general student population."
Blomstrom departed with a positive mindset.
"The linebackers coach is going to keep in touch and was glad to see me," he said. "They're going to sign four linebackers and are coming to watch me during the spring, which is encouraging.
"Their defense is based out of the 3-4, which wouldn't be hard to adjust to."
Blomstrom, who has ties to Louisiana, visited LSU last fall and will return to Baton Rouge next month for the Tigers' junior day.
"I want to get to know more about LSU," he said. "I've been talking with Coach (Thomas) McGaughey.
"The linebackers coach at Oklahoma has asked about me, and I think we'll probably attend junior day there and at Texas Tech."
Blomstrom, already a two-year starter at Katy, helped the Tigers to a perfect season and lofty national ranking in 2012.
