Arkansas and Texas will try to create some separation from each other in the minds of the NCAA Tournament committee when they square off Wednesday in a key Southeastern Conference game in Fayetteville, Ark.Differentiation is important for both teams because each owns a 16-11 overall record and a 5-9 mark in SEC play.Arkansas carries a modicum of momentum as it looks for the season sweep of the Longhorns after a 92-85 home win over then-No. 15 Missouri Saturday. Zvonimir Ivisic scored a game-high 20 points while Johnell Davis hit for 18 points and snatched four steals, D.J. Wagner produced 17 points and Karter Knox added 14.”Every game in this league is ridiculous — let’s see if we can build on this,” Arkansas coach John Calipari said. “Everybody watching this team knows we’re getting better. Now we just gotta finish.”Razorbacks forward Adou Thiero’s status for the Texas game is in question after he aggravated a back injury late in the second half. Thiero, who scored 11 points against Missouri before being forced from the game, averages 15.6 points, six rebounds, two assists and 1.7 steals per game this season — all career-high marks.”If Adou doesn’t play, well, then next man up,” Calipari said Monday. “Come on, somebody else. One guy’s misery is another man’s opportunity. That’s how you look at it.”
