The formal naming of a new coach yesterday by the Cincinnati Bengals began to sharpen the focus on the coaching picture in Baltimore. A development might occur Sunday in Dallas that could be pertinent.

When the Bengals turned the reins over to Forrest Gregg, Mike McCormack, offensive line coach, immediately emerged high on the list of those being considered to coach the Colts.

If the Dallas Cowboys eliminate Los Angeles from the playoffs Sunday the Colts expect the Rams to fire Ray Malavasi and hire George Allen, who might offer a job to Ted Marchibroda, fired Thursday by Baltimore.

One Ram faction favors trying to hire John Robinson of Southern California if Malavasi is fired. But the faction favoring Allen is believed to have the ear of Georgia Rosenbloom, owner of the Rams.

Besides Marchibroda, two other Colt coaches, Maxie Baughan and Dick Bielski, once were assistants under Allen.

Presently, Allen is not under consideration by the Colts.

But among the past and present pro coaches who are are Hank Stram, former head man at Kansas City and New Orleans, and George Perles, assistant head coach of the Pittsburgh Steelers.

College coaches the Colts regard highly are Joe Paterno of Penn State, Frank Kush, until recently at Arizona State, George Welsh of Navy and Wayne Hardin of Temple.

Baltimore is just about convinced that Paterno will not leave Penn State.

No member of Marchibroda's staff will be offered the head coaching job, it was learned.Nor is Dan Reeves, offensive coordinator of the Cowboys, under consideration.

The Steelers said the Colts have not asked permission to talk to Perles, but acknowledged that they told him a few days ago they would not stand in his way when it was reported that he was on the Bengal's list of possibilities.
