By "pure" rb, means he can do it all. Meaning he can run (obviously), catch and pass protect.
Because of the style of offence the Cougars (Charlotte Catholic) run, the Wing T, Hood doesn't need to catch the ball or pass block. His strict duty is to pound the rock. Now, it's been observed by many scouts at camps and The Opening, that Hood has really soft hands and made some pretty tough catches in traffic, and some acrobatic ones too. But, you don't get to see that on film, because like I said, his job is to just run the ball. Not much receiving and little to no blocking involved in Hood's game.
If Bryant and Hood were in the same recruiting class, I'd probably say that Bryant would see the field first barring injury. For RB's to see the field at ND, Kelly has said that they must be able to pass protect, or they won't be on the field. Bryant's abilities are a little more advanced than Hood's at this point in time, but that doesn't mean Hood can't be on Bryant's "pureness" level, just that he was some work to do first!
Lol "pureness" level...
