Darrell Green, CB, Texas A&I

Green is 5 feet 9 and weighs 170.

The defensive coordinator at Texas A&I says that "it's impossible not to gasp in amazement" when watching films of his punt returns at Texas A&I, a Division II football power in Kingsville, Tex.

"He does stuff that is physically impossible," Fred Bleil said. "He'll turn people completely around and then cut across the grain and just flat outrun folks. When he takes the field, people hold their breath, because they know something exciting is going to happen."

But the Redskins picked Green more for his ability as a cornerback than as a kick returner. He is expected to move into Joe Lavender's spot as nickel back and he'll also challenge Jeris White for a starting spot. Green compares physically to former Redskin star Lemar Parrish, who also was a standout returner in college. Bleil said Green "is tough and physical. You don't worry about his size."

Green, who will be the quickest player on the Redskins, beat Stanley Floyd in a meet last month. He lives in Houston and attended Jones High School, where he was all-state in track and all-city in football.

At Texas A&I, Green intercepted 15 passes in four years and was the Lone Star Conference defensive player of the year last season. He has four career touchdowns on returns and two more on interceptions. He finished last season with a 20.6 average for 19 punt returns, tops in Division II. He averaged 22.7 on 19 kickoff returns and had four interceptions. Richard Williams, RB, Memphis St.

Williams, a 6-foot, 217-pounder who runs the 100-yard dash in 9.6 seconds, was injured throughout his time in college, which curtailed his performance on what were very poor teams.

This selection probably surprised a number of other NFL teams, because Williams was not consistently rated highly in this draft, which had many good running backs. The Redskins had him ranked 28th in the draft. (He was picked 56th).

He led Memphis State in rushing last year, gaining 480 yards for a 5.4 average. In four years, he gained 1,092 yards, averaging 4.8 yards. He scored six touchdowns and caught 34 passes for 279 yards.

As a sophomore, he averaged more than 100 yards for four games; in the fifth game, he broke a leg and was out for the year. Prior to the injury, he had rushed 189 yards in three quarters against Georgia Tech, including a touchdown run of 76 yards. The next week he gained 100 yards against Louisville.

He later broke the same leg in a different place and had a lengthy rehabilitation. That limited him to 37 carries his junior year, for 117 yards.

"The main question about him is his production in college," Coach Joe Gibbs said. "Everything else is legitimate."

Don Breaux, the Redskins' backfield coach, said that Williams "has good speed, he protects the ball and he has good hands. He should fit in real well in our one-back offense." Charles Mann, DE, Nevada-Reno

Mann is 6-6 and weighs 240. General Manager Bobby Beathard calls him "a hot property," which means that a lot of NFL teams were interested in him the final weeks before the draft. That's one reason the Redskins took him in the third round, fearing they'd lose him if they waited until their next pick, in the sixth.

Playing against Division I-AA competition, Mann was the Big Sky Conference defensive player of the year for two straight seasons. Last year, he led the conference in sacks with 14.

"You look for a guy like him to dominate against this kind of competition, and he did," Beathard said.

But Mann's development was hindered by constant switching between linebacker and end. "I really wanted a chance to play linebacker in the pros," he said. "But with the Redskins, I'm going to be strictly an end."

In his first year at Nevada-Reno, he was a defensive tackle. He moved to outside linebacker as a sophomore, then played both spots as a junior before staying at down lineman his senior year.

Mann, who played at 215 pounds during some of his college career, now weighs 245. "Even though I'm 6-6 and 245, I feel small," he said. "I've got to get bigger and gain 15 more pounds. I don't want to get hurt up there."

Mann, who comes from Sacramento, Calif., was timed in 4.89 seconds for 40 yards on a bad field this spring. He is considered a pass rusher with good size, speed and what scouts call "great explosion."
