It's getting to the point where cord cutting isn't guaranteed to be cheaper anymore because of everyone having their own streaming platform. You still have to have an ISP to watch at home which isn't that cheap, and usually more expensive per month when not bundled with another servoce. You'd need a subscription TV service and decent one is going to start at about $50 per month and up because not all include a sports package with channels like FS1, CBS Sports, or NBC Sports. Then you'd need an ESPN+ subscription to see games like the one KU was supposed to play yesterday which is either $60/year or $6/month. Depending on which subscription package you go with, an antenna to pick up local channels when KU plays on CBS, ABC, or Fox.
Ballpark, you're probably still looking at around $150 per month specifically to watch KU and that doesn't other streaming services like Netflix or Disney+ that could easily push a monthly bill to the $200 per month range.
Decide what all you want and price it out because it's getting to the point where cutting cable isn't guaranteed to be cheaper anymore depending on which subscriptions you have/want.
