THE LONGEST TRANSITION IS FROM SATURDAY TO SUNDAY.

Craig Newmark notes that Ryen Russillo doesn't quite answer, "Why Is It So Hard to Draft NFL Quarterbacks?" Nor does he shed any light on what the supply elasticity of quarterbacks is.

It's not quite true that "For every [c.q.] Patrick Mahomes, there’s a Mitchell Trubisky."  It's more like 28 busts to 22 successes with five borderline hires in the past few years of first-round draft choices according to Mr Russillo, who watches Saturday pro football, er, the Southeastern Conference, regularly.

His assessment: the position is a difficult one to learn, and the usual quantitative stuff isn't precise enough to pick winners. (The extension to Ira Magaziner style industrial policy ought to be straightforward, but I digress.  There are cameo appearances by Ben Bernanke.)
