I am of the opinion that every writer, analyst and expert covering any field should make specific predictions for which they should be held accountable. As it stands now, writers in particular sometimes have little incentive to make accurate predictions. With no skin in the game, what's to stop them from simply making bold claims for the sake of drumming up controversy?
If all writers were forced to make very particular prognostications and then revisit those predictions to see where they went right and wrong, there would be a pretty strong incentive (pride and reputation) to get it right.
Most important, it would help readers understand who knows what they're talking about and whose content is full of fluff. It's really easy to look back on past events and analyze them after the fact, but it's an entirely different endeavor to put yourself on the line in predicting what will take place in the future. It's easier said than done.
This idea is why I make a number of very specific preseason predictions, as well as scrutinize the predictions after the season.
I say "at the time" because I think my 2013 predictions were even more accurate. I've listed the majority of them in this slideshow, both good and bad. I actually believe the predictions that go wrong are much more valuable because 1) I can determine if I indeed made a mistake (sometimes you can make a great prediction that simply doesn't pan out) and 2) I can tweak the models or numbers I use to make predictions to enhance future accuracy.
