What a player ranked coming out of high school is completely irrelevant when evaluating a prospect especially when it's non-scouts that are making such assessments. This is not even a consideration in the scouting world or NFL draft rooms. Carson Wentz only had one scholarship offer, NDSU. That's also like saying the Patriots/Steelers shouldn't pay the best QB/WR in the league because they were 6th round picks. They must not be worth it because they weren't elite amongst their peers coming out of college. There have been hundreds of 4-star QBs that were elite among their peers all their life that failed. Aside from Trevor Lawrence & Justin Fields, the other 8 of the top 10 high school QBs of all-time are Vince Young, Brock Berlin, Terrelle Pryor, Matt Barkley, Jimmy Clausen, Mark Sanchez, Russell Shepart, & Brodie Croyle are all NFL/college busts.
The NFL draft is about upside. Dillard has tremendous upside & was graded as the best pass protector in college football this year. Murray is a 5'9 180lbs QB. That's not a good size for any position on the field. Optimal height for an NFL QB is 6'3. The exceptions Brees (6') & Wilson (5'11) are three inches less that optimum height, Murray is SIX. You realize how big of a height difference that is? That's like asking Steph Curry to guard Lebron. Too much height to overcome.
