Mike Mularkey was the Steelers OC from 2000--2003. Under Mularkey’s guidance, Pittsburgh finished third and fifth, respectively, in the NFL in total offense in his first two years in the post, and led the league in rushing offense (173.4 ypg) in 2001. Also that year, quarterback Kordell Stewart threw for 3,109 yards and was selected to the AFC Pro Bowl squad. The Steelers went 13-3 in 2001, captured the AFC Central Division title and played in the AFC Championship game. In 2002, Mularkey oversaw the resurgence of quarterback Tommy Maddox, who, after having not played in the NFL from 1996-2000, completed 234 of 377 passes for 2,836 yards with 20 touchdowns and 16 interceptions and was named NFL Comeback Player of the Year. Maddox’s 62.1 percent completion mark that year was a franchise single-season record at the time.
Prior to being elevated to offensive coordinator, Mularkey spent his first five years in Pittsburgh as the team’s tight ends coach. During that time, he oversaw the development of Mark Bruener, who was regarded as one of the premier run-blocking tight ends over this stretch. In Mularkey’s five years as the Steelers’ tight ends coach, Jerome Bettis shattered the 1,000-yard rushing plateau each time and the Steelers as a team placed in the top ten in the NFL in rushing offense every year, including a No. 2 finish in 1996 and a No. 1 ranking in 1997.
Mularkey was head coach of the Bills and is currently the TE's coach for the Miami Dolphins. Mularkey was also the one who started using the "trick plays" that the Steelers popularized. This was continued by Ken Wisenhunt, but has pretty much stopped with Bruce Arians.
Of course I would be happy to take the OC position with a salary of 100,000, but my credentials are pretty poor, but I have hundreds of playbooks and watch coaching videos all the time. Plus I remember the offense of the 70's with Bradshaw, Harris, Bleier, Swann, and Stallworth.
