I am IN FAVOR for several reasons of expanding the daily match limit to six. I do see some situations that would have to be worked around, especially as it relates to competition with out-of-state schools that would adhere to the five match rule.
But, comparing wrestling to football (or any other sport) is a "straw man" argument. Football is a series of 15 to 20 second bursts of activity followed by 20-30 seconds of relative inactivity. Wrestling is, by far, more physically intense.
To take the offered analogy one step further, high school basketball games last 32 minutes, so should the total daily wrestling time be reduced to match that?
