Im having problems knowing whats the difference between the USA TODAY/ESPN poll,AP poll,and RPI poll for NCAA mens basketball

I don't know the difference but the common element of both is that they are both pointless.
nothing
different voters in the usa/espn and ap polls. rpi is the ratings percentage index and it takes in numerous polls and figures.
USA Today poll is voted on by the coaches. AP Poll is voted on by members of the press. RPI - The Rating Percentage Index is a mathematical measurement of a team's strength. The formula consists of a team's winning percentage against Division I opponents (25 percent), the opponents' average winning percentage (50 percent) and the opponents' opponents' average winning percentage (25 percent). It gets a little more detailed, but those are the main points.
Not much. Just a bunch of old men who feel the need to be the source, to be controlling. We all have our own polls...
