Ok, go down the list and tell me what years other than his first two, did he have better than a 2 to 1 ratio. http://www.pro-football-reference.com/players/M/MariDa00.htm He usually attempted up to 50% more passes than Henne? Henne averaged 470 attempts the last two years. 50% more would be 705. 470 + (470/2) = 705 or very close, right? 470 + 235 = 705 Dan went over 600 attempts 3 times. 606, 615 and 623. So he never even once attempted 50% more than Henne's avg attempts.
1983, 1984, 1987 (2:1 exactly, good enough for me), 1993. But like I said, Marino attempted more passes per season than Henne, yet wound up with a lower INT %.
1993 was 5 games, ok I missed that. But you did say better than 2:1. 26/13 is not better. Also like I edited in, he never attempted 50% more passes than Henne's avg in two seasons starting.
