As previously noted, Bill O'Brien and Doug Marrone coached together at Georgia Tech. Marrone was at Tech from 1996 through 2000 LINK
and O'Brien from 1995 through 2002 LINK George O'Leary was head coach from 1994 through 2001 until he was hired away by Notre Dame (discrepancy on his resume killed that contract) Tech enjoyed a good bit of success in the O'Leary era, though success is a relative thing. We're talking about Georgia Tech. The bowl record from 1997 through 2002 was 3&3. The won the conference in 1998 with a 7-1 record, 10-2 overall. I found all that at this link

. O'Leary's second season saw the emergence of Joe Hamilton as starter when Brandon Shaw struggled in his first two starts. Hamilton would eventually lead the Jackets back to bowl contention and Tech attended its first bowl in six years, the 1997 Carquest Bowl.

Hamilton's prowess as a runner and passer thrilled the Georgia Tech fans. Offensive coordinator Ralph Friedgen utilized a complex offense with Hamilton that featured option football mixed in with complex timing routes. Hamilton racked up yardage, touchdowns, and wins for Tech. In 1998, Hamilton and Tech's high powered offense won 10 games and a season ending victory over Notre Dame in the Gator Bowl. Hamilton's senior year put him on the national stage. He was a leading candidate for the Heisman Trophy against rushing phenomenon Ron Dayne. Hamilton passed for over 3,000 yards and rushed for over 700 yards.[44] But while Hamilton dazzled, the Georgia Tech defense was a liability (they allowed around 28 points per game), and may have ultimately cost Hamilton the 1999 Heisman Trophy. In a late-season, nationally televised game against Wake Forest, Tech gave up 26 points and Hamilton threw two interceptions and no touchdowns. As an indirect result, Dayne went on to win the Heisman (Joe was runner-up). Hamilton's Georgia Tech career ended on a sour note in the 2000 Gator Bowl against the Miami, where the Jackets lost 28–13.[45] The following season, redshirt junior George Godsey, a more traditional pocket passer, succeeded Hamilton at the helm of Tech's powerful offense. The drop-off was minimal—Godsey continued where Hamilton left off, winning 9 games in 2000 and 8 games in 2001. In 2000, Godsey also led Tech to their third straight victory over the archrival Georgia Bulldogs.[46]

So apparently Tech had a pretty good offense during their time there, option and then more traditional pro set. In my lifetime Tech has never attracted elite players like UA does so I'm pretty confident they will do well at Alabama.
