Mac Jones, Penei Sewell, and the possible death of Draftniks

So one thing I was thinking about while reading a few mocks last night is that the "draftnik community" absolutely refuses to believe that Jones could ever possibly go at 3 to SF. Most mocks have him tumbling to around pick 10, I supposed as some sort of "frick you" to the belief that NFL front offices seem to really differ in opinion about Jones.

On a similar note, the media and draft industry seem to have pumped up Penei Sewell as basically a more athletic Joe Thomas. If this were true, he would never go past 4 and likely would go 2 (because after Lawrence, the QBs aren't nearly as elite as they're being pushed by the industry). He has some serious red flags (arm length for one) and may tumble past 6 or 7 in the draft. Lots of message board posters are convinced of things like the Bengals ONLY logical option is Sewell because...guys less experienced than Mel Kiper said so for a year.

So, if Jones does go 3 and Sewell does fall in the draft, does this do severe damage to the draft industry? Like with all other niche areas, the amount of draft content has exploded with a major increase in "experts". However, if they are, almost unanimously, this wrong about 2 guys compared to the NFL, doesn't that do irreparable damage for the current content creators? This is Mel Kiper being wrong about Clausen, but across an entire industry. Is the group think that bad, where it's largely an echo chamber now created by the loudest guys 2 years before the actual draft? Has the NFL developed new analytics that surpass anything that these creators could even hope to comprehend?
