IRVING, TEX., OCT. 7 -- After today, the Dallas Cowboys could finally say they don't miss Herschel Walker anymore. Rookie Emmitt Smith put up Walker-like rushing numbers and scored the game-winner on a 14-yard run to rally the Cowboys to a 14-10 victory over the Tampa Bay Buccaneers.

Smith rushed for 121 yards on 23 carries. "I showed myself a little today," said Smith, the 17th pick in the first round out of Florida. "But I didn't get an opportunity to shake and bake like I like to do. I think I can do much better."

Smith missed training camp and had 104 yards on 37 carries before today.

Dallas (2-3) broke a three-game losing streak and snapped the two-game winning streak of Tampa Bay (3-2).

Smith's yardage is the most by a Dallas back since Walker gained 134 against Cleveland in l988. Walker was traded to Minnesota last year.

The 73-yard drive early in the fourth period was set in motion by a seven-yard, third-down scramble by Troy Aikman for a first down on the 50. On the next play, he hit fullback Tommie Agee with a 30-yard screen play. Then Agee threw the clearing block on Smith's touchdown run.

"The blocking was outstanding because it allowed me to get inside then I could bounce to the outside," Smith said. "That's how you get into the end zone."

Vinny Testaverde, the NFL's leading passer coming in, couldn't bring the Buccaneers back. He was sacked three times, but did hit hit 13 of 19 passes for 194 yards.

Tampa Bay went ahead by 10-7 in the third period when Testaverde hit Gary Anderson with a 58-yard pass on which free safety James Washington fell.
