The rules were equally pass happy back then, which is a big part of why Marino got 48 in the first place. They put the same "emphasis" on the rule in either 83 or 84.They did it again in the mid 90's and you had some ridiculous numbers for a few seasons there. Favre was putting up his ridiculous numbers, Rice had the best numbers of his career - even Isaac Bruce caught 1700 and something yards.I think what the '05 Bears did in spite of these pass-happy rules is as impressive, if not more impressive, than what the '85-86 Bears did.
Had they played their starters, they'd likely have stayed at 168 allowed and it wouldn't even be a debate. Instead, that 34 point backup shalacking mitigates comparisons for many.
