The thing that is missing from his game is making tacklers miss, being elusive, getting yards after contact. It's hard for me to get on board with a guy as a potential superstar when he doesn't do that very well.
His combination of pass catching, size, strength, and speed are obviously the story with him and that's been the case since he was in high school. He's also a good student of the game and a thoughtful kid. It's enough that you can forgive a flaw, even if it's a pretty big one.
Ballage had some really poor offensive line play in front of him and I don't think it was a coincidence that he blossomed at the Senior Bowl.
There is a bit of David Johnson in him, for those of us who evaluated Johnson with foresight back in 2015 (when he was a late-3rd round pick coming out of University of Northern Illinois) rather than those of us using hindsight from 2018.
My goal for him this year since he's so big, strong, and willing, would be to get him good enough at blocking that I could use him in 21 personnel looks as a second running back that can play upback, split out wide, take carries in short yardage, and pass protect while Kenyan Drake runs out on routes.
If you watch what the Rams did with Robert Holcombe in 1999 under Mike Martz (mentor to Adam Gase), that's the vision.
