Yeah, the different sites will have different guys rated higher than others, and it will also look much different in April than it does now. Personally, I prefer PFN's simulator to TDN's, but they have some guys rated lower than they probably should.
We can only work with the board they give us though. Yeah, Moore is probably going in the first, and Harris could go early in the second, or even late in the first, but again, we don't have control over that.
Also, there are guys that drop. Humphrey seems to be going early in these mocks, as high as 10th, but he certainly could drop, as IOLs seem to do so often.
Also, as far as Parsons is concerned, he could be there at 7. Remember a couple years ago, when the Jags got Josh Allen at 7? Who saw that coming?
