It looks like Arkansas might be the team Coach Pitino was blogging about.
You may recall that about a month ago, Coach Pitino released his first blog post of the off-season. In it, he said that Minnesota was in negotiations for a new home & home series with another Power 5 team:
We are currently working on completing our nonconference schedule for next year. We believe we will be on the road for the Big Ten/ACC Challenge and playing in the Gavitt Games against a Big East team. We have a verbal agreement from another Power 5 team to start a series at our place.
