That Bengals team was also responsible for the current injury/timeout rules in the NFL. During a playoff game against Seattle (I think in '88, maybe '89) the Seahawks defensive players kept getting 'injured' after almost every play in order to substitute against the no-huddle. After that year, they started putting the rules in place they have currently, ie you get a 'free' injury timeout per half if the injury stops the clock, after that it's a charged timeout, a penalty, and/or a 10-second runoff depending on the situation...
It's funny how it was considered controversial back then that Wyche was being 'unsportsmanlike', whereas now the Colts offense is just 'innovative'...
