You're so screwed up about Geoff Torretta. He WAS higher than third string. He was the backup to Vinny in 1986. If you remember--which you apparently don't--Geoff transferred to Miami as a junior after playing at Diablo Valley C.C. in California. Jimmy Johnson was desperate for an experienced backup. Kyle Vandewende had thrown in the towel after losing his apparent starting job succeeding Jim Kellyand Marc Richt in '83, and left. Vinny was Bernie Kosar's backup for the '83 and '84 seasons. When Bernie left, Vinny inherited the starting job in '85, and all we had were true freshmen Steve Walsh and Bill Turkowski. Neither of these two touted freshmen were ready to be the backup.
Jimmy Johnson found Geoff Torretta, who was more experienced at the college level and recruited him as a juco transfer in 1985. When he was signed, but before he arrived on campus, Johnson spoke publicly about Geoff and said that he expected Geoff to be Vinny's backup when he arrived. He did serve as Vinny's backup in '85 and '86 and played a major role for our '86 team, which was one of the best in college history and should have been the NC for '86 except Vinny fell apart mentally in the Fiesta Bowl against PSU. (Some suggested after the game that we would have won the NC had Torretta played QB for us!)
One of the most important games in UM history came on Thanksgiving Night in 1986. Vinny had fallen off his motor scooter and suffered minor abrasions, but was too banged up to play. Geoff started that Thanksgiving Night nationally-televised game and beat East Carolina. That preserved what had been a perfect season up until that point.
Incidentally, I just noticed that the wikipedia article on Steve Walsh erroneously describes Steve as Vinny's backup that year. He was not. If you consider the backup the next guy to come in to play, the no.2, that was definitely Geoff. He was never third string in the two years he was at UM.
We went through some rough years in terms of QB depth after Kosar and Vandewende left. One year, I can't remember which one, we were so thin that we brought back a punter, Kirk Sandifer, to be our third string QB. He had already left the program but he had a year of eligibility left. That's how desperate we were.
Turkowski never worked out. He tried being a pitcher for Ron Fraser. He eventually transferred back home to Pitt where he finished his career as a TE.
So, no. Geoff was never third string. He was always second string. And that clutch Thanksgiving Night victory in '86 is one of the more memorable games in UM history.
