Through the bit I read at Buckyville and through a UW fan I know with 247, he stated it is confirmed that Caleb has met with UW coaches. It also sounds like Russell Wilson talked with Williams about how Paul Chryst and Wisconsin’s pro style offense prepared him for the NFL and made him a top tier starter sooner. For what it's worth, I haven't seen anything from an actual "large news network" reporting this, like ESPN, CBS, etc. Not sure if that matters. In regards to Russell Wilson, when he came to UW, here is who was on the roster with him.
Nick Toon
Melvin Gordon
Jared Abbrederis
James White
Montee Ball
Bradie Ewing
Derek Watt
Chris Borland
Beau Allen
All NFL players
His offensive line options. Everyone of these guys played in the NFL as well.
Ricky Wagner
Tyler Marz
Peter Konz
Josh Ogelsby
Kevin Zeitler
Travis Frederick
Rob Havenstein
Ryan Groy
That ain't the Badgers in 2022. Good luck Caleb.
