Today's the day Texas corrections officials return Bullet Bob Hayes to society; 321st day since the once-fastest human, not to mention Cowboy, arrived in Huntsville penitentiary for dealing cocaine, he is paroled to "involve himself in charity work and some drug-related education work" . . . Mike Hogan, top Eagle rusher of 1976 and '77 booted off the team by Coach Dick Vermeil after a drug bust in suburban Philadelphia last June, is off the hook. A Camden, N.J., judge dismissed the single charge against Hogan, an injured San Francisco 49er last season, saying merely discussing price of narcotics didn't constitute crime.

Mel Proctor, radio voice of the Bullets, has won the job of play-by-play man on Texas Rangers radio and TV, with the understanding that Washington's NBA team retains first call on his services for the next two years . . .

One less big name in NASL '80: Kyle Rote Jr., taking a leave from the Houston Hurricane "to regenerate myself mentally and physically." But, heck, he scored only one goal all last season . . .

On the way to the NCAA: Jim Mitchem, starting forward for No. 1 De Paul, slipped on an icy patch on route to class yesterday, fracturing a bone in his left hand. Might face Notre Dame tonight, anyhow, with a splint over ring and little fingers.
