Yes. There are some problems with this method (e.g. in 2011, when 3 teams with great minibots were on an alliance), but I don't think there's a better way to do it.

Also, just for fun, 2012 OPR (used teams' average of all event OPRs, but they're all pretty similar) is predicting 2013 matches at about 61% (counting any rookies as OPR = 0). Thanks to Ed for the OPRs and Ether for the Twitter Match Data. Not sure what I'd do without you two.

Edit: I don't want to post too many times, but there's a couple different things here. One is OPR as a tool to predict what will happen. Ed's reply below is pretty much exactly what I do for predicting matches (except realtime OPR; that's something I'd like to do in the future). In this case, I'm talking about how well OPR evaluates teams this year vs. other years, for which I used post-event OPRs. You can't hit 80% predicting matches without realtime data.
