Georgetown got off to phenomenal starts in both halves and routed Grambling State, 77-30, in a college basketball game tonight in Ewing Coliseum.

The sixth-ranked Hoyas are 4-0 after their 33rd consecutive victory over a nonconference opponent.

Grambling, which had not played Georgetown before, took a 2-0 lead after a minute and it was downhill from there. The Tigers (3-1) shot 18.8 percent from the field.

Grambling's leading scorer was freshman Charles Price, who had eight points.

"I never evaluate what we gain in a game until after I evaluate the films," the winning coach, John Thompson, said. "The opponent is the game and you have to take into consideration that (Grambling Coach Fred) Hobdy has a lot of freshmen playing. I used to always ask myself what did we gain by playing people in 1972. Now, people are asking themselves what do we gain by playing Georgetown?

"There are a lot of things we are trying to accomplish. I don't look at it in a positive way. I look to identify problems and I'm sure when I look at the films, I will see some problems."

Reggie Williams led the Hoyas with 11 points as 11 Georgetown players scored. David Wingate and freshman Johnathan Edwards each had 10.

The Hoyas took a 22-2 lead, then in the second half came out with a 28-6 blitz in which the Tigers did not score for 8 1/2 minutes. The Hoyas' defense was so good that they quit pressing in the second half.

Thompson used nonstarters nearly the entire second half and most of the first half. The Hoyas forced Grambling into 29 turnovers and had a 54-40 rebounding advantage.

"We played totally scared," Hobdy said. "There's no way we could be that bad."

It was the fewest points Georgetown, which has won its four games by an average of 35 points, allowed since New England College scored 30 in the 1977-78 season.

At one point, Georgetown led by 49 (71-22 with 7:09 to play).

"It verifies that we are very inexperienced," Hobdy said. "I'm not making any apologies, but I don't think that we were as inexperienced as we were afraid."

He had said earlier this week that he feared a blowout in the early minutes.

The Hoyas scored 10 of their first 11 times down the court, mostly because their defense set up fast breaks.
