The Richmond Spiders will look to continue their improbable run through in the 2011 NCAA Men's basketball tournament when they face top-seeded Kansas in tonight's Sweet 16 matchup in San Antonio.

The Spiders defeated Vanderbilt in the second round and another upset team, Morehead State, in the third round. However, tonight's contest should be a major challenge for the Spiders.

The Jayhawks have only lost two games all season, and are riding a 10-game winning streak.

Illinois had kept the game close in the third-round game, but Kansas broke it open inside the final six minutes to handily defeat the Fighting Illini, 73-59.

Kansas will have a low-post advantage over Richmond tonight, thanks to the Morris twins, Marcus and Markieff. The two big men, who are both about 6'9 in height, combined to shoot 16-for-26 from the field for 41 points, and also added a combined 24 rebounds.

Richmond also has height in senior starters Justin Harper and Dan Geriot, who are listed at 6'10 and 6'9 respectively. There will be a great deal of focus on how Harper and Geriot contain the Morris twins tonight.

Harper is considered a possible first-round draft pick in the upcoming NBA Draft.

The Spiders have another valuable senior starter in Kevin Anderson. The guard has averaged better than 16 points per game over the past three seasons, and scored 25 points against Vanderbilt.

Prior to a 14-point performance against Morehead State, Anderson had scored 21 points or better in four straight games.

Bill Self has told his Jayhawks squad not to overlook Richmond. Kansas and Ohio State are the only remaining one seeds left in the tournament, and both could meet a similar fate to Duke who lost to Arizona on Thursday.

If there is a criticism of Kansas's squad this season, it would be the inconsistent play of its guards.

Josh Shelby, a much-heralded freshman, has seen his minutes significantly decline in recent weeks.

The winner of this game plays the winner of Virginia Commonwealth-Florida State on Sunday.
