In the April 19 issue of ESPN the Magazine, Peter Keating discusses a way for NFL teams to determine whether or not a first- or second-round QB will have a successful NFL career. (Insider subscription required.)
David Lewin, formerly an analyst for Football Outsiders and now with the NBA’s Cavaliers, has found that games started and NCAA completion percentage accurately predict NFL performance for QBs drafted in the first two rounds. To be more specific, the Day 1 QBs who go on to have the best pro careers complete at least 60% of their passes and start at least 37 games in college.
This theory has been around a while and when I was researching it last week, I stumbled across a similar article from 2007, so I’m not exactly sure how far back it dates.
Using college completion percentage makes a lot of sense. It seems intrinsically true that a QB that has trouble completing passes in college is also going to struggle with his accuracy in the NFL.
The number of starts is another strong stat. For a prospect to start 37 games, he basically needs to be a three-year starter. This indicates that he’s been around the block a few times, is reasonably durable and opponents have had a chance to game plan for him (and he’s still completed a high percentage of passes). It also seems reasonable to think that most good NFL quarterbacks wouldn’t have to be a backup for more than one season while in college.
Let’s take a look at the QBs selected in the first and second rounds of the ten drafts spanning from 1998-2007 to see if this theory still holds water.
