The Baltimore Colts may not win many games, but new Coach Ted Marchibroda will always be a hero in crabcake country. The Steelers, remember, kept Marchibroda one year and released a rookie from Louisville by the name of Johnny Unitas. General Manager Joe Thomas has promised not to interfere with Marchibroda, who spent the past nine years handling the offense for George Allen. Bert Jones will get better protection than he received last season, when Colt quarterbacks were sacked 49 times; in fact, Baltimore's new offensive line, featuring Tackle George Kunz, acquired from Atlanta, and top draft Ken Huff at guard, is the strength of the attack. Lydell Mitchell, who caught 72 passes last year, many of them safety valves from harried quarterbacks, may get running help from rookie Roosevelt Leaks. As always, Middle Linebacker Mike Curtis is the Colts' defense. WE WILL ARRIVE IN '75 read the bumper stickers in Baltimore. They might rate by '78.
