Definitely worth 15 minutes of your time.
On the NFL Combine:
"A recent study confirms that it is largely worthless: 'Combine measures examined in this study include 10-, 20-, and 40-yard dashes, bench press, vertical jump, broad jump, 20- and 60-yard shuttles, three-cone drill, and the Wonderlic Personnel Test . . . . Using correlation analysis, we find no consistent statistical relationship between combine tests and professional football performance, with the notable exception of sprint tests for running backs.'"
"Despite the banalities, the inane chatter by talking heads, the useless combine and Wonderlic, the terrible state of football statistics for measuring what all twenty-two players did on a given play and how well they did it, the NFL draft…works?"
