Baylor added a national-best ninth Quadrant 1 victory on Saturday with an 80-63 win over Texas — but it wasn’t all good. While doing so, the Bears lost a key player, Jonathan Tchamwa Tchatchoua, perhaps for the season.

Tchamwa Tchatchoua has never started a game in two seasons at Baylor, but that fact doesn’t properly reflect how important he is to the Bears. The big man was averaging 21.5 minutes per game this season, 2.2 minutes more than he did in the 2020-21 campaign. He’s a key piece that matters. If his knee injury is indeed season-ending, Baylor’s attempt to become college basketball’s first back-to-back national champion since Florida in 2006-07 will obviously become even more difficult than it already was going to be.

Baylor remains No. 6 in Sunday morning’s updated CBS Sports Top 25 And 1 daily college basketball rankings. The Bears have six regular-season games remaining — among them Quadrant 1 opportunities on the road at Texas Tech, Oklahoma State and Texas with a home meeting scheduled against Kansas.

Onto the Power 36 with a new No. 1 team (previous ranking in parentheses):

1. Gonzaga (2): The Zags are absolutely crushing WCC competition.
2. Kentucky (4): The Wildcats have the current front runner for national player of the year in Oscar Tshiebwe.
3. Arizona (8): The Wildcats swept three road games at Arizona State, Washington State and Washington.
4. Auburn (1): The Tigers dropped a road game at Arkansas in overtime. No shame in that defeat.
5. Kansas (7): The Jayhawks are currently the new favorite in the Big 12.
6. Duke (6): The Blue Devils did lose at the buzzer to Virginia but they pass the eye test of being a title contender.
7. Purdue (3): The Boilermakers had a brutal week with three games and the loss at Michigan seemed to be an anomaly. This team is tired.
8. Illinois (5): The Illini are having trouble with Purdue and that’s about it when they’re healthy.
9. Providence (10): The Friars have a two-game lead on Villanova with a major showdown against the Wildcats Tuesday night.
10. Villanova (13): The Wildcats are primed for a showdown with the Friars Tuesday night.
11. Baylor (17): The Bears did beat Texas handily but lost Jonathan Tchamwa Tchatchoua to a season-ending knee injury.
12. Ohio State (12): Yes, I know the Buckeyes lost at Rutgers. But they finished the week with an impressive win at Michigan.
13. Texas Tech (15): The Red Raiders did lose to Oklahoma but then rebounded to knock off TCU.
14. Wisconsin (16): The Badgers lost at home to Rutgers, but earlier in the week did win at Michigan State.
15. Tennessee (23): The Vols are back in the good graces of the poll and moving up in the SEC.
16. Arkansas (20): Yes, the Hogs lost to Alabama but earlier in the week they knocked off No. 1 Auburn.
17. USC (28): The Trojans shot up in the Power 36 after knocking off rival UCLA.
18. Alabama (26): The Tide is turning toward ‘Bama in the SEC with wins over Arkansas and Mississippi State.
19. Texas (21): The Longhorns got past Kansas but couldn’t get over Baylor.
20. Wyoming (22): The Pokes have won six in a row and are now the team to beat in the Mountain West.
21. UCLA (14): The Bruins slide back after losing to rival USC.
22. Notre Dame (25): The Irish have won four in a row and have a one-game lead for second place in the ACC.
23. Murray State (34): The Racers have won 14 in a row. KJ Willaims scored 39 points in a win over Tennessee State last week.
24. Michigan State (18): The Spartans ended the week with a home win over Indiana after a loss to Wisconsin.
25. Miami (NR): The ‘Canes are back in the top 25 of the Power 36 after winning at Wake Forest.
26. SMU (NR): The Mustangs are now in first place in the AAC after beating Houston.
27. Houston (9): The Cougars had a rough week losing to SMU and Memphis. But they have been running on fumes and deserve one bad week.
28. UConn (27): The Huskies had a wild week with a win over Marquette, a frustrating loss at Xavier and then a road win at St. John’s.
29. Rutgers (NR): The Scarlet Knights aren’t in the field just yet, but are firmly on the bubble after beating Ohio State and winning at Wisconsin for their fifth and sixth Quadrant 1 wins.
30. Memphis (NR): Penny Hardaway has the Tigers back in position to get an NCAA tournament bid after winning five in a row and beating Houston.
31. Oregon (19): The Ducks take a tumble after losing to Cal at home. But the Ducks are still an NCAA tournament team — barely.
32. VCU (NR): The Rams have won six of seven and are in a position to overtake Davidson in the A-10.
33. San Francisco (35): The Dons have won five of six and look like an NCAA tournament team.
34. Colorado State (NR): The Rams have won four in a row since falling at Wyoming.
35. Boise State (24): The Broncos fell at home to Colorado State but are still in a position to get a bid.
36. Virginia (NR): The Cavaliers have won four in a row, including stunning Duke at Cameron Indoor Stadium to get back on the bubble.

Dropped out: Marquette (11), Washington State (29), Wake Forest (30), Saint Mary’s (31), Indiana (32), Davidson (33), Ohio (36).
