You're right that the comp is a little unfair given the age difference and development curve.
But Miles Infrastructure is becoming a classic 3&D wing, with the driving and passing chops to be a borderline all-star. He was touted as a strong versatile defender. And the questions were about his scoring ability. But he's really rounded out his offensive game, playing with extreme confidence, and has become consistent. We'll see if he can sustain this level of play all season, but he was doing it the end of last year too.
RJB keeps adding to his game.
As a rook, started off as a transition weapon, man defender and strong driver going left.
2nd year took a significant leap as a defender, especially close-out and switching D. Which meant his D was pretty solid across the board, except for allowing backdoor cuts, which has continued this year as his man gets parked in the corner and then RJB drifts too far or becomes inattentive to his man. 2nd half of last year, RJB became a fairly deadly 3 point shooter.
Now RJB has a better handle and can drive right some. Has shown more passing chops, both kickouts and lobs to Mitch. This is a bit inconsistent in his game, but the progress is certainly there.
Future: Some more work on his handle and passing. More consistency on his outside shooting. And overall, try to develop more consistency between and during games. Try to avoid lapses in concentration on both ends. Consistency is the hardest thing to achieve for young players, and really all players. But often differentiates the top of the line players from the good. RJB already has a pretty nice two way game. Is young and hard-working. Promising.
