4 OA picks going back to 1980:
Didn't particularly research this, I'm sure you could argue a few guys up/down from their brackets or within their lists. Makar and B Tkachuk seem to be trending to the top 2 brackets, but still early.
To me, Bennett is right in the middle of this list, with lots of potential to move up or drop down. A more interesting analysis would be to see what age each of these guys 'became who they were'. I don't think many forwards in the 'hmmm' group had 4 seasons of 10+ goals by age 23.
Semantics, but I don't think he's a bust, but rather a disappointment.
edit: initially had Dylan Strome (3OA) instead of Marner
