I got those numbers from CBS, but I agree that they are wrong because this post prompted me to do the calculation myself.
For those who want to know the formula, it is [(8.4*yards)+(330*TDs)+(100*Comp)-(200*Ints)]/Attempts
I double checked your stats for those games and they were correct. I ran the formula against those numbers and here is what the math produced:
Fromm - 190.3
Murray - 188.9
Funny that I got the same calculation for Murray, but not for Fromm. Not sure what you did wrong, but I did the calculation 3 times and got 190.3 each time. Feel free to run the numbers again.
Finally, the UMass game - Fromm barely played. He threw only 5 passes, had only 106 yards in that game, and only 1 TD. Yeah, it moved his score up about 7 points. But he also had games against Kentucky, Auburn and Alabama in there. Those games, against very good defenses, really hurt his score.
So, once again, Fromm was the best QB in the second half of the season. It negates many of your posts in this thread. I know that it hurts, but it is a straight fact.
Murray is the best QB in the history of history - and that is a scientific fact!
