CoachJW wroteTo defend him, our opponents have to hand check, bump, and push him
If your opponents are effecting his rhythm, speed, quickness, or balance, then these are, most certainly, fouls.

Is it possible that he is able to "get through" the contact, and thus, even with the contact, he is able, with his speed, to get past his opponents. If so, the officials may be seeing this as incidental contact, with no advantage gained by the defense, and thus, no foul.
CoachJW wrote... he's obviously unable to get where he wants to go
Some strong, quick players don't avoid contact, especially if they know that they can "get through" it. If it looks like a pinball game out there, he may be creating some of the contact, not enough for a player control foul, but some of the contact may be of his own volition.
CoachJW wrote... when they see the scoreboard say that the fouls are 4-0 in mid-first quarter, they back off on the whistles
This is 100% poor officiating. Are these young officials that you are discussing, or are they veterans?
CoachJW wrote... the officials consciously or subconsciously don't want to "be here all night" by putting one team in the bonus that early
Consciously, or subconsciously, this is poor officiating.
CoachJW wrote... they want the fans to see that the game is being called fairly by making the fouls closer on the scoreboard
Once again, good officials don't do this.
CoachJW wrote... tougher and stronger than his opponents
Again, if it's a pinball game out there, he may be creating some of the contact.
