Tailback Eric Dickerson rushed 200 yards and scored touchdowns of nine, 80 and 79 yards to lead fourth-ranked Southern Methodist to a 47-9 homecoming victory over fumbling Texas A&M in a Southwest Conference game at Irving yesterday.

The Mustangs (8-0 overall and 5-0 in the SWC) have won 12 straight, the longest winning streak in the NCAA Division I.

It wasn't the Aggies' day. The teams have played each other 61 years and this was the worst defeat SMU has inflicted. A&M (4-4, 2-3) fumbled three of the first five times it had the ball, surrendered a safety after a goal-line stand and failed to cross midfield until five minutes into the second half. Mistakes provided SMU's first 16 points.

Even worse, four minutes into the game, quarterback Gary Kubiak of A&M chipped a bone in his left ankle.

The only good news for the Aggies came after the game, when doctors found that Kubiak wasn't hurt as badly as first thought. They said he might play again in two weeks.

Coach Bobby Collins of SMU praised Dickerson after the regionally televised game: "He continues to make the big plays. Now that people have had the opportunity to see him on TV, they know what we've been talking about all along."

"That last touchdown run capped off a great afternoon," Dickerson said. "I'm catching a plane tonight for (his hometown) Sealy, Texas, to just get away a while. I need to clear my mind. But I do love all the attention."
