For the chance at having Major League Baseball & the NCAA Hoops season occur on the same day, Philadelphia will need to force a Game 7, and then both teams need to be ultra competitive enough to extend a Game Seven into Monday EST. While that's a long shot, the 2022-2023 season gets underway on Monday, November 7th, 2022.
As is the custom, the big events before the turn of the year are the Championship Classic AND the CBS Sports Classic.
The Championship Classic, slated for Tuesday, November 15th, features (per tradition) Duke, Kansas, Michigan State, and Kentucky. Those schools combine for 19 National Champions in the modern era of the game (23 overall I believe), and a ton more Final Four appearances.
The CBS Sports Classic, slated for Saturday, December 17th, features (per tradition) Kentucky, Ohio State, North Carolina, and UCLA. The Buckeyes and Bruins were unable to compete last year but should be good to go this year.
There will be several early season Tournaments that may or may not affect one's participation into the postseason. Aside from that, most of everyone will play non-conference games prior to the all but exclusive conference games from around the New Year through the end of February into the beginning of March. While the regular season concludes on Selection Sunday (March 12th, 2023), the week leading up to that date will feature conference tournaments; most will conclude the Saturday before & a couple on that Sunday. That's mainly the Big conferences; some of the others could wrap up early in the week or even a week plus before.
The Postseason gets started on 03/14 & 03/15 with the first four (on TruTV). The main part of March Madness gets underway on Thursday, March 16th, 2023. The first two rounds take place on TBS, CBS, TNT and TruTV from 03/16 - 03/19, and the following week, the Regionals take place from 03/23 - 03/26 on TBS & CBS.
The NCAA Tournament will conclude the following weekend featuring the winners of the games played on March 25th & March 26. The Final Four starts on April 1st, and it concludes on April 3rd with the National Championship game starring the winners of the 04/01 games. CBS has exclusive coverage of the tourney's final three games.
A couple big notes from this season. It's the first season since 1979-1980 without Coach K on the Duke sidelines, and the defending champions in Kansas will get things going without their head coach. Bill Self has been suspended, part of Kansas self-imposed punishment. Villanova coach Jay Wright has called it quits as well; I believe he is slated to do some work for Turner & CBS during the postseason, which he has done in the past.
Finally, while several do not watch the game for the announcers, this will be Jim Nantz final season working the Final Four. Back when, the 38 season CBS Sports vet would become the face of the CBS Sports; however, his basketball duties decreased while he rose in the NFL. Plus his PGA duties overlap, which helps result in Jim calling one regular season game (Big 10 senior week, used to be the NCAA Hoops season premiere that led into Army/Navy; sometimes both). He's slated to call the Big 10 semis & championship game before being part of the A-Team for the NCAA Tournament. Ian Eagle, who has been the biggest fill in (while Nantz was working PGA), is expected to replace him full time. In hoops (Nantz will still do NFL game and the PGA & the Masters).
I have no idea who'll win this year. I might just wait and pick someone when I fill out my bracket
