Not only that, in the TL;DR blurb at the end of the article he says:
"The final spot in this projection comes down to a sixth running back (Perry) or receiver (McKenzie), a fifth defensive end (Harold) or a fifth safety, with Neal being the choice"
Obviously, that would be six running backs? insane.
Personally, I think we run with 7 WR's next season
The main 5 (Robert Foster, John Brown, Cole Beasley, Andre Roberts and Zay) and a Gadget Option + Big Target (McKenzie or Vic Bolden) and (David Sills or Duke Williams)
