Grading my own preseason predictions.
Just about every writer that covers a specific sport does some kind of preview article for said sport. It is low hanging fruit, paint by numbers, writes-itself kind of stuff. It is also great fun and a chance for the author to stretch their legs and show off the "great wisdom" that they have. All of which is a really big deal, ...until the first game that renders most of it useless old-news.
Because it is useless after the first game, writers rightfully discard it as old news. But not me! I like to go back and prove to everyone what an idiot I am.
