The people that say Hutch won't get drafted are living in another universe.
He's not the speediest receiver, but he's not slow (40 time of 4.5 or whatever). He's not the biggest receiver but he's not small. More importantly he runs great routes, NEVER gives less than 100%, and catches every kind of ball imaginable.
Let's look at someone like a Mike Evans, someone who has 1.5 to 2 inches on Hutch but is also a little bit slower. Evans had the benefit of playing during Manzielmania but caught every ball that was in his vicinity. He parlayed that into a 7th overall pick selection and has been nothing but a model of consistency (at an ultra high level) since.
Elite quarterbacks like Brady, Mahomes, Rogers, etc want guys who are where they are supposed to be and, when the ball is put on target, make the plays. I see absolutely no reason why Hutch can't or won't run great routes and continue to catch everything at the next level. If he runs sub 4.5 (which I think he will), shows at least a decent vertical, and impresses during team interviews he will 100% get drafted. Moreover teams would be incredibly dumb to even let him slip to the 5th round.
IMO the 3 most sure fire NFLers we have are McDonald (easily number 1), Kolar, and Hutch. If any player will be unduly hurt by metrics it will be Rose, I also see him succeeding at the next level (constant contributer with a long career).
My biggest question mark is Breece. He has excellent vision but needs a zone blocking team to fully utilize those talents. He will be drafted but I have no idea as to where he will or possibly even should go.
