Dalby was the 100th overall pick of the
1972 NFL draft, selected in the
fourth round by the
Oakland Raiders. He played fourteen seasons in the NFL, all with the Raiders (
1972–
1985) and did not miss a single game. In his fourth year in
1975, Dalby replaced
hall of famer Jim Otto as the
starting center, who retired after the
previous season. He became only the second starting center in franchise history, as Otto had been the starter since the team's inception in
1960. For the next decade, Dalby was a part of sterling offensive lines which culminated in three Raider
Super Bowl victories (
XI,
XV,
XVIII). During that 1975–1985 window, the Raiders reached the playoffs eight times (1975–1977, 1980, 1982–1985). During his eleven seasons as a starter, Dalby played next to hall of famer
Gene Upshaw,
Curt Marsh, and
Charley Hannah at left guard with
George Buehler and
Mickey Marvin at right guard. He was selected to the
Pro Bowl once, after the
1977 season. After his retirement, he was replaced as the starting center in
1986 by
Don Mosebar. ==Death==
