Possible rule changes, NCAAM style...

[Nevadaref]

One item noted is a potential change in guarding position for block/charge decisions from prior to airborne to the start of the upward movement as in the NBA.

Why is this a desirable change?

-----------------
"We feel this would help referees and also reduce the number of charge calls," the source said."
-------------------
First, the article doesn't attribute the quotes to anyone, just "the source," which is frustrating.
Second, how would this help referees? They still have to determine if a defender was in position prior to some other action occurring. At least when the feet leave the floor is clear on video and thus the decision now has a clear point at which to evaluate it. If they go to upward motion, it will be much more vague.
Third, the source says that this will reduce charging calls. Probably true as it would certainly tip the balance in favor of the offense, yet it isn't explained why this would be an improvement or positive. Is a charging foul a bad thing which should be more rare?
Seems that the NCAA is considering this for three reasons:
1. Because this is the way that the NBA does it.
2. More defensive fouls would increase scoring. There were several articles on the low-scoring college game lately.
3. Related to point 2, the low-scoring is seen as undesirable and that people don't enjoy watching the games, thus don't buy tickets and the product is less marketable. The hope is that changing some rules to increase scoring will lead to making more money.
