There's only so much you can know heading into a draft. Prognostication is an inexact process. Though tons of time and resources go into scouting college players—and the interviews teams conduct at the Scouting Combine are intense, to say the least—there will always be a degree of uncertainty surrounding the draft.
The best draft analysts tend to get things right for the most part. They've been at it long enough to know whether most players will succeed at the next level.
Sometimes, however, they spew terrible opinions. They say a guy is going to be a bust, and then he turns into a league MVP. For example, consider the time a Houston NFL writer wrote that the Texans would "rue the night" they picked J.J. Watt over Nick Fairley.
Yeah...bad prediction, man.
There is little accountability for these analysts. If they repeatedly get things wrong, we'd like to think they wouldn't keep their job, but there's no standard measurement system.
Seahawks cornerback Richard Sherman thinks there should be one. Sherman called out draft analysts on Twitter Tuesday afternoon, stating that many of their predictions are "idiotic."
All these draft analyst get so much wrong. I wish someone kept track of how idiotic some of their predictions are. They literally spew of ton of nonsense and get paid for it. Wish they got graded and paid for how often they are right/wrong— Richard Sherman (@RSherman_25) February 27, 2018
In case you're wondering why he cares: Sherman somehow fell to the fifth round of the 2011 NFL Draft. He turned into a four-time Pro Bowler and unequivocally one of the best corners in the league.
In 2013, he called the NFL draft process "a sham."
