Below is a quick analysis of some Upon Further Review (UFR) Plus/Minus data from MGoBlog. Brian from MGoBlog breaks down the offensive and defensive plays from the previous week’s game and assigns “pluses” to positive plays from players and “minuses” to mistakes. It’s not unlikely he gets things wrong here and there, but overall it seems to be a reasonable and in-depth assessment of a players effectiveness. For more detail I highly encourage you to head to the site and read his work, if you are somehow reading this and not already deeply familiar with it.
I’ve acquired data for every game he’s charted, though I have only broken down the +/- data so far, which does not take a QB’s passing quality into account, nor details like route running for receivers. I will get to some of that data in the future, but keep in mind that the main assessment of offensive skill players is missing from this data currently.
Also, keep in mind that there is only data for games that Brian wrote up a UFR, so there may be some bias comparing years due to games left out because he was too sad to look back at them.
(As a note: I also plan to post an interactive visualization for others to use in the near future. I will hopefully deploy it in the next few days.)
I’ve split the pages up to be a bit more readable:
