All this genius under one roof and still there were serious differnces of opinion today as to which of the 28 clubs "won" the National Football League draft of college players.

Dallas may prove its right to the claim on the basis of the trade for the rights to draft Heisman Trophy winner Tony Dorsett.

But most of the professionals conceded that Cincinnati, Pittsburgh and Green Bay helped themselves considerably.

Cincinnati, which had three picks in the first round, used them to select defensive tackles Eddie Edwards of Miami, Fla., and Wilson Whitley of Houston and tight end Mike Cobb of Michigan State. On the second round, they got big fullback Pete Johnson to go with former Ohio State teammate and Heisman Trophy winner Archie Griffin.

Pittsburgh chose lineback Robin Cole of New Mexico, running back Sidney Thornton of Northwest Louisiana, defensive tackle Tome Beasley of Virginia Tech (rated highon the Red skin lost) and wide receiver Jim Smith of Michigan.

Green Bay used its first two picks to take defensive ends Mike Butler, a Washingtonian who played at Kansas, and Era Johnson and Morris Brown. Brown also was rated high by the Redskins.

A remarkable note was that no one was drafted from Grambling or Notre Dame. Nor were there are players selected from Ivy League schools.

The University of Maryland came to the fore this year with five players drafted - defensive end Joe Campbell, in the first round by New Orleans: running back Tim Wilson and guard Ed Fulton, in the thrid round, by Houston and Los Angeles, respectively; guard Tom Schick in the sixth round, by New Orleans, and offensive tackle Dave Conrad in the 12th round by the New York Jets.

There were only 335 players drafted in 12 rounds because Houston forfeited its fifth-round pick for a violation. There were 190 offensive players selected, 145 for defense, including 13 placekickers or punters. The breakdown: 52 running backs, 46 defensive backs, 38 linebackers, 37 wide receivers, 29 offensive tackles, 25 guards, 25 defensive ends, 23 defensive tackles, 18 quarterbacks, 18 tight ends, 11 centers, 10 placekickers and three punters.

There were 14 players picked from Southern California; nine from Colorado; eight from Boston College; seven each from Kansas, Baylor, and Georgia: six from Nebraska, Michigan, Purdue, Arkansas State and Pittsburgh, and five from Oklahoma State, San Jose State, Memphis State, Arkansas, Oklahoma and Tennessee State.

By conference it was Big Eight 41, Pacific Eight 36, Southeastern Conference 31, Southwest Conference 29, Big Ten. 28, Atlantic Coast 15, Southland nine, Mid-American and Pacific Coast Athletic Association eight.

Erich Barnes, a former Chicago Bear and New York Giant cornerback who is now a players' agent, said the Bears' expertise might have been overlooked.

It wasn't until the sixth round that quarterback Vince Evans of Southern California finally was chosen by the Bears. Three of Evans' teammates have gone in the first round - running back Ricky Bell, offensive tackle Mary Powell and defensive tackle Gary Jeter.

Lineback Dave Lewis went in the second round the wide receiver Shelton Diggs and guard Donnie Hickman in the fifth.

Evans was the first player taken in the sixth round, just ahead of defensive back Mike Burns, even though Evans led the Trojans over Michigan in the Rose Bowl.

Barnes observed, "I know people are going to say I'm saying this about Evans because he is black and I am black. But he was the best passer in the nation at the end of the season. He was just unlucky that he played with a team that did not pass much."

A check with another club about its list of prospects turned up the information that Evans was listed as both a quarterback and a defensive back.

But Bear general manger Jim Finks said Evans was drafted as a quarterback.

"We called Evans on Tuesday night ," Finke said. "We had him rated as an outstanding athlete, who came on real fast as a quarterback in his last year, who could be gold in time.

"Bob Avellini is a fine prospect and we traded with Cleveland on Tuesday for another veteran, Mike Phipps.

"(Bear coach) Jack Pardee talked to him and told him that he indeed will be given a chance to become a quarterback in this league.

"I talked to Evans' agent and cited cases such as Paul Hornung, who came into the league to be a quarterback but played better at another position."

Asked about Evans' preference Finks said the player insisted on being tried at quarterback.

"He is a highly intelligent young man," Finks said. "He apprenticeship. I don't feel that Evans is as good a passer yet as . . . Barnes says . . . but he is a good quarterback. He has a strong arm."

In trade developments, St. Louise sent a seventh-round choice to Cleveland for defensive back Neal Craig.
