One of sport's more famous theories is the one about a letdown. It's hard for a team to keep playing at a sky-high pace, especially after a loss.

Arkansas almost proved the theory before asserting itself against Texas Tech Wednesday night.

The third-ranked Razorbacks were playing for the first time since having their 20-game winning streak broken by top-ranked UNLV on Sunday.The only thing Texas Tech and UNLV have in common is two-word nicknames starting with `R.' Yet, the Red Raiders had Arkansas down for 28 minutes before the Razorbacks rallied for an 87-69 victory.

"It was hard for us to get up for this game, especially after playing UNLV," Arkansas' Todd Day said. "This is a big win for us.

"Coach was worried because he didn't think we would be emotionally high enough to play this game. We just came out flat and didn't do the things we normally do."

That Arkansas (24-2, 11-0 in Southwest Conference) came out flat was an understatement. The Red Raiders (8-17, 4-8) led 10-1 and 15-3 and Arkansas didn't pull even until there were four minutes left in the half.
