Bracketology: Florida State is your newest No. 1 seed, Kentucky falls to a No. 3 seed

Also, Michigan State is out as of now and its margin for error to get back in is miniscule

Monday and Tuesday are usually relatively quiet days during a college basketball week. Not this week. The results of five big games have churned both the top and bottom of the bracket.

Starting at the top, Villanova, the overall No. 1 seed Monday, blew a big lead and lost at Marquette on Tuesday. The Wildcats are still on the top line, but are now the overall No. 3 seed. Villanova still has a high number of quality wins and Marquette has played itself into the middle of the bracket in the last couple of weeks.

Kansas used to be that third team on the top line, but the Jayhawks got smoked at West Virginia. They have six top-50 RPI wins, but only three of those are against teams in the bracket, and the win against Duke in the second game of the season is the only one over a sure tournament team. Kansas finds itself down to a No. 2 seed this morning.

The new overall top two seeds are Baylor and Gonzaga, which moved up past Villanova and, in Gonzaga's case, Kansas. The Bears had the good fortune of not having played the last couple of days. Gonzaga throttled Portland on Monday night.

The fourth, and newest, No. 1 seed is ACC leader Florida State. The Seminoles have an unmatched seven RPI top-25 wins (the next closest is four) and nine top 50 wins.

Kentucky lost at Tennessee on Tuesday night as well, making it the first time since 1979 that three of the top four teams in the AP Top 25 lost on the same night. The Wildcats can't afford losses like this if they hope to stay high in the bracket. They just don't have too many chances for quality wins to make up for it. Kentucky fell down one line to a No. 3 seed.

Kansas is at Kentucky on Saturday, and with both teams coming off losses, this game has even greater bracket implications for both teams.

The churning at the bottom of the bracket started Monday night, when a rapidly spiraling Duke team gave away a big lead at home to North Carolina State and lost to the Wolfpack 84-82. That was just what NC State needed to push back into the bracket. The Wolfpack now have wins at Duke and at home against Virginia Tech and fellow bubbler Pitt. In a weak bottom, that's enough to have them in for now.

Michigan State fell out of the bracket entirely after losing 84-73 at home to Purdue (what a show Caleb Swannigan put on) on Tuesday night, a loss that Tom Izzo was, uh, not happy about. The Spartans' 19-year streak of tournament appearances is in serious jeopardy. They are sitting at 12-9 after the loss, which isn't a good enough record to get in the field, but of greater concern is that with 10 regular-season games left and the conference tournament, the loss count is getting precariously high.

If the Spartans need an at-large bid, that requires a loss in the conference tournament. That would mean MSU would need to win seven of those final 10 games just to finish with fewer than 14 losses. Only seven teams in the past 23 years have received an at-large big with 14 losses, and five of those came in 2011, the first year that the tournament expanded to 68 teams. No 14-loss team has received an at-large bid since. The time for Sparty to get hot is now.
