Roundball chatter

Each week, I write about the sport I love, college basketball:

• Congrats to the Big East and Big Ten for setting up the Dave Gavitt Tipoff Games, which will help launch the 2015-16 season. It is great to see the two conferences doing battle with intriguing early matchups. There are fewer Cupcake City games early when leagues square off in a series of games like this. It has the potential to enhance rivalries like Georgetown-Maryland, Xavier-Ohio State and Butler-Indiana. It could also lead to the renewal of the St. John's-Rutgers rivalry. (Creighton and Nebraska already meet regularly.)

• Florida-Kansas and Kentucky-Texas will headline the matchups in the SEC-Big 12 Challenge. This is another example of interesting showdowns that help the sport.

• Another positive for fans is a December event set up for each of the next three years. Kentucky, North Carolina, UCLA and Ohio State will participate in the CBS Sports Classic. This year's event will take place Dec. 20 at the United Center in Chicago. It will be held at Barclays Center in Brooklyn in 2015, while Las Vegas will host in 2016.

• Oregon State decided to make a coaching change as Craig Robinson was let go. The Pac-12 has seen three coaching changes overall. California hired Cuonzo Martin from Tennessee to replace Mike Montgomery (who retired), and Washington State hired Ernie Kent to replace Ken Bone.

• Staying in the state of Oregon, three Ducks have been dismissed from the team due to poor decision-making. Damyean Dotson, Domenic Artis and Brandon Austin have to know right from wrong.

• Former Maryland guard Seth Allen has decided to transfer to Virginia Tech. Score one for new Hokies coach Buzz Williams.
