Why would Al Davis want to move his Raiders out of Oakland Coliseum, where he has sold no fewer than 50,000 season tickets for the last 10 years in a stadium with a capacity of 54,615?

Other National Football League executives survise that Davis envisions himself as attaining in glamorour Los Angeles the status of the late Carroll Rosenbloom, whose pregame and postgame parties included a Who's Who of celebrities.

Other big names are missing at the ownership level in Los Angeles -- Jack Kent Cooke, Walter O'Malley, Dan Reeves. Big newsmakers among the coaches are also gone -- George Allen, John McKay, John Wooden. The likes of Tom LaDora and Jim Fregosi wouldn't threaten Davis' posture.

Davis has made a spectacular trade already -- Ken Stabler for Dan Pastorini -- to offset the sudden emergence in the Super Bowl of a new star in Ferragam of the "Anaheim Rams."

Look for a sort of "leak" soon to inspire recurring speculation that Allen may become the Raiders' coach, in an attempt to rival the Rams for prestige.

If Davis' projected move to Los Angeles is defeated in the courts, look for him or Gary Davidson, of World Football notoriety, to link up with Big Time Operator Ted Turner of cable television in starting a new league.

Pro football is so popular that the NFL's contract with CBS brought a record fee for a network radio sports package -- $12 million over four years, a tribute to announcers Jack Buck and Hank Stram.

In the spring, a young man's fancy turns toward weight consciousness and what he will look like taking a sun bath. Dr. Richard Passwater, nutritionist and author of "The Easy No-Flab Diet" offered to Muhammad Ali (Richard Marek Publishers, New York), writes that, "Every year at the beginning of summer camp, the Redskins are given thorough examinations, including percent-body-fat calculations based on skin-thickness measurements.

"Some teams even use underwater weighings ot measure total body fat since fat floats (the lighter you weigh under water, the fatter you are."

Amid changes that greed prevails at all levels in sports, Donnie Harris, Mark Murphy, and Mark Moseley of the Redskins; Bob Windsor, former New England Patriot, and former Redskins Eddie Brown and Dan Ryczek are raising money for charity playing basketball for the WMAL "Oneders."

Wide receiver Rich Mauti of New Orleans donated $1,179 he earned from special teams performances to the American Cancer Society and appreciative fans combined to boost the aggregate to more than $8,000.
