I agree that actually witnessing something would be better, if you are trying to make a judgement.
however, not witnessing the act does not preclude you from having an opinion.
I can learn enough from the statistics, NFL situation at the time, overall talent on a team, team success, views of contemporaries, etc to make a judgement with regards to how "great" a player was.
maybe not EXACTLY, but I can learn enough to know that Bradshaw was a good QB who has gone down in history as an alltime great. that is what this thread is about
This is where you lose the argument.
You are using statistic to determine the value Bradshaw had to those teams.
You have to have seen those teams play to know the value within and behind those statistics.
Here is an example.
You judged Terry Bradshaw by cumulative stats for 10 years, plus your impression that the Steelers had a great defense.
If you had seen them played and followed football in that era. You would have a better grasp. Bradshaw was the #1 pick in the draft, by clearly the worst team in the NFL, and he struggled a lot early in his career. By the time the Steelers starting winning (a year or 2 in) Bradshaw was playing better but was erratic. In 1974 when they won their first SB, they were a running team with a great defense. In 1974 he was the beneficiary of QBing a great team. In 1975 he had a very good year. He became the leader of the team, and made many plays to be the difference in them winning. At the least he was an above avg QB who had an above avg impact on winning. In 1976 Bradshaw was injured, came back and the Steelers went to the AFCC, but Bradshaw as well as both RBs missed the game, and they got destroyed. By 1978 the Steeler defense and running game were not NEARLY as good as you believe them to be. They were still good, but Bradshaw was the guy who made the difference, and the Steelers were among the best passing teams in the league. Bradshaw was ABSOLUTELY regarded as one of the best, unquestionably the strongest arm, and the toughest QB. They repeated in 1979 when the running game and D slipped further. For the rest of of his injury abreviated career he kept them in the hunt, and as soon as he was gone, they didn't sniff success for a long time.
During the first 2 SBs the Steelers were more of what you think they were, but during the last 2 Bradshaw was more important than anyone on the team.
Now, your other criteria is careeer stats.
Lets consider a few things:
1) Bradshaw was thrown in as a rookie to a terrible team and spent his first couple of years getting beaten alive. That is a factor in stats.
2) Bradshaws ability to amass numbers was affected by his career being cut short, somewhere in the vicinity of his prime, by a career ending injury.
3) If Bradshaw had not had that injury he would have plauyed many more years. (He was injured in 1982 at 34 years old. You are comparing him to QBs who played until their very late 30s)
You say Tarkenton was better because of all the numbers he amassed. Tarkenton played early in his career on some bad teams (as did Bradshaw) but he was on Viking teams that were every bit as good defensively over a 4-5 year period as the Steelers, and had a very comparable running game.
If you had watched, you would have known that Tarkentons teams were well known for choking in big games, when they were the better team. Tarkenton ABSOLUTELY had the table set for him to win 4 SBs equally as well as Bradshaw did.
The difference is while Bradshaw played parts of 14 years and 170 games, Tarkenton played 18 full years and 246 games.
Since you are devaluing Championships (the reason they play the game) by saying someone else could have won them that never won one, I suppose I can devalue stats (the reason people who don't form opinions from watching people play use to replace their own analysis) by saying that if Bradshaw was throwing for somewhere around 225 yards a game when he was injured, if he stayed around long enough to play as many games as Tarkenton, he would have an additional 17,100 passing yards, and be within 2000 yards for his career of what Tarkenton had, and had 4 rings to none.
I'm going to tell you with 100% certainty that anyone who watched and followed football in that era would never come close to saying a team had a better chance of winning a SB with Fran Tarkenton at QB than Terry Bradshaw.
Does your opinion change when you recognize this?
Does your opinion change when you realize all your ranking is based on is that Tarkenton played longer. (Or does longer equal better?)
Does your opinion change when someone who was there tells you the Vikings were every bit as good as the Steelers, but Tarkenton couldn't play in the big game?
By the way, aren't you also discounting Troy Aikman because he didn't play as long as the other guys? What is better about Tarkenton, Marino, Elway than Aikman other than number of years?
