Mal Moore (1971-1982) under Bryant and 1990-1993 under Gene Stallings
In the summer of 1970, Moore not only had an offense handed to him it was also taught by Texas coaches. Bryant's switch to a wishbone produced three national championships in the 1970s. The Crimson Tide lost only 11 games in the decade. Moore was a significant contributor to the Tide's wishbone success and the scapegoat for Alabama fans and Bryant every time a play failed.
Moore's return to Tuscaloosa in 1990 under Stallings produced an efficient offense that won the National Championship in 1992.
Homer Smith (1988-1989) under Bill Curry and (1994-1995) under Stallings
Homer Smith was one of the most highly respected college football offensive minds of the 20th century. His 1989 Alabama offense, quarterbacked by Gary Hollingsworth, arguably did more with less than any Crimson Tide offense ever.
The marriage between Gene Stallings and Homer Smith was flawed from the start due to differing offensive philosophies. Stallings had little appreciation for Smith's West Coast offense and fired Smith after the 1995 season.
Smith died in Tuscaloosa in 2011. Afterward, Ivan Maisel wrote about him, "Homer Smith may be the most revered college football coach who ever won 53 games in a 12-year head-coaching career... across five decades. He achieved little fame but garnered, among the coaches who worked with him and the writers who covered him, an enormous amount of respect and adoration... the best football coach I’ve ever seen" was how Bill Curry described Smith. Maisel reminded that Curry played for Bobby Dodd at Georgia Tech and Vince Lombardi at Green Bay.
