With the 49ers apparently in another quarterback controversy, I wanted to take a look at how Steve Young and Joe Montana did in the six years they were both 49ers: 1987 through 1992. Of course, Montana was the regular starter in the first four seasons, Young the starter in the last two. For passing by the two:
Young started 36 games and played in 62, with a 26-10 record as starter. He had 641 completions on 1005 attempts, 63.8%, for 8660 yards and 65 touchdowns. He threw 21 interceptions, had 8.6 yards per attempt and 13.5 yards per completion, and had a 104 QB rating.
Montana started 52 games and played in 56, with a 43-9 record as starter. He had 1111 completions on 1722 attempts, 64.5%, for 13626 yards and 103 touchdowns. He threw 47 interceptions, had 7.9 yards per attempt and 12.3 yards per completion, and had a 97.4 QB rating.
For rushing from ’87 through ’92, Young ran 248 times for 1611 yards, 12 tds, a long of 49 yards, and 6.5 yards per attempt. Young’s rushing yards per game were 26; he had 20 fumbles.
Montana ran 165 times for 690 yards, 8 tds, a long of 20 yards, and 4.2 yards per attempt. Montana’s rushing yards per game were 12.3; he had 19 fumbles.
In terms of regular season record for a six-year span, the ’87 through ’92 49ers might be unmatched in NFL history (I haven’t checked to be sure of that, but they’re at least close). They were clearly capable of winning four Super Bowls in those years, maybe five, and having two great quarterbacks available for most of their games was a big part of their success. The 49ers had an amazing luxury of talent in the six seasons.
