As a Mizzou fan and alum I've seen all but one game (Colorado -- their only previous weak showing that resulted in a close win). If you watched their other games you would know a few things about them. 1) At least half the teams in the SEC have more talent. 2) They are, for the most part, neither fast nor quick and have only mediocre ball handling. 3) They had NEVER played against the ball pressure they saw from Tenn. Warlick has been under a lot of pressure to have her team play up to their talent (I've also watched all but two of the Lady Vols games) and she admitted she has been keying her practices for a couple weeks around this first SEC matchup. They took Mizzou totally out of their game in the third quarter and they never recovered. The picks, and cuts, and plays that got them open threes (the kind their many good perimeter shooters need to be effective) against non-ranked teams would not work against a quick, physical and well-controlled press. This was Tenn's best defensive performance of the year, by far.
In essence, Mizzou paid the price for a weak non-conference schedule. But if you watched their other games you'd know that they are a better team than they showed on Monday (and Tennessee is a better team now than when they lost to Va Tech, at least defensively).
Missouri has no allusions about where they are. But winning those 13 straight to start the year has helped attendance and built some media interest. They won't beat the South Carolinas and Kentuckys on their schedule. And probably not even the Miss States and A&M. But if they can beat Auburn, Vandy, Ole Miss, Alabama, Auburn, Arkansas and Florida, they'll finish with 18 or 19 wins and a top seven finish in the SEC and that will land them their first NCAA bid in a long, long time -- and that's their goal for this year.
On a good night they CAN shoot the three, and the inside game is much improved. Freshman Cunningham and Porter are the highest ranked recruits in the team's history. Pingeton is a very good coach who has them playing team basketball and the team chemistry seems to be very good. Pingeton almost always plays at least 10 or 11 players in virtually every game. There is not a single senior in the starting five nor among their top scorers. It's too early to say whether they'll reach their goal this year or not. And they've been prone to injuries the past few years.
As far as being a Top 25 team...they would have passed the eye test up until Monday, but their best win was probably a convincing victory at St. Mary's, a team that beat Cal. Once you get past about the first 7 or 8 teams, though, there's not much to choose from. Look at Stanford's recent games. Or Kentucky's loss to Auburn. Or Duke. Louisville has looked awful once or twice and ND struggled against Pitt and Baylor lost to OkSt who then lost to IaSt. This year, more than ever perhaps, it's all going to be about the match-ups and consistent play. Mizzou now goes against a much improved Georgia and then two Top 10 teams (SC and MissST). So, yeah, that 13 and 0 and #20 ranking may well change to 13 and 4 and unranked real quick. And, of course, those are the games that will be the most watched on the tube. But because of their modest goals, Mizzou's most important games will actually be the ones they play against the LOWER-rated SEC teams and they'll need to show some consistency there if they want that top half conference finish and an NCAA bid. (Charlie Creme has them as an #8 seed, and they'd be tickled with that!)
In all honesty, the Mizzou program right now reminds me a bit of UConn right after Geno came in the late eighties when I lived in CT and would take my daughter to the games in the Fieldhouse and then in Gampel. The biggest difference might be that the Big East back then was a weak conference for women's basketball with even the strongest teams -- Providence and Villanova -- being early tourney outs, while Mizzou has to deal with a very strong SEC. I think Mizzou's SOS rating now is well into the 200's; but by the end of the year it's projected to be in the top 35. And, by then, we'll know how good this team really is.
