While I liked so many players ahead of Richards at that 64 slot (AJ Cann, Jaelen Strong, PJ Williams, David Johnson, Sammy Coates), I think it hasn't been remarked upon in this thread that Richards was slated as a 3rd rounder by many analysts up until a few weeks before the draft when he started dropping in the composites.
I imagine that once the "mockers" start to see a player drop, they then jump the bandwagon and the player really starts a slide. So I ask, what made the consensus believe he was a 3rd rounder only 3 or 4 weeks ago? Why did he become a 5th/6th rounder leading to the draft? Is it groupthink? We don't know. Similarly, Cody Prewitt was a composite first rounder. Then dropped to the 2nd round only a couple weeks before the draft, and right before the draft, he was end of 3rd round. Ended up undrafted.
I still don't like the Richards pick but we have to at least mention that he was considered as high as a 3rd rounder by a great deal of people only weeks before the draft.
