I think Pritchard is better than Waters in some areas, but waters stylistically plays a different kind of point guard.
For rookies they are both relatively square and confident when they are responsible for the point on offense. Often Pritchard plays with the starters and thus, is off the ball. This does not exploit his ball handling and passing. Steven's reasons for this are obvious, veterans are going to handle the playmaking and PP gets his occasional wide open three.
Looking at Water's contribution this season might add something to the discussion.
When Water's is on the floor and also, the odd games he's started, Waters brought the ball up.
This is his second year, last season he was the G league MVP or whatever he won, but, played few minutes in Boston.
Next season, will Pritchard play in Maine? I don't think so, but I will say that Stevens does not give him many minutes.
My point, Stevens ball distribution schemes don't seem to be about point guards.
When all of the bench is on the floor? Teague or Waters would bring the ball up, but, is that because Stevens runs things differently with the bench on the floor?
to address triboy's query, I offer little beyond how Stevens uses Pritchard and Waters...(who, BTW are both really accomplished NCAA point guards who got drafted)

For you math lovers Pritchard played about 6 X the number of minutes as Waters so go down the line.
Waters would win the assist per game battle 360 to 120
Waters just has the ball in his hands more.
Pritchard is now used as a shooting guard and Waters is the point guard. Whatcha gotta do to get rookie minutes...right?
I agree that these two players are small. I also insist that they are both excellent shooters and passers and can "run the floor" as point guards under pressure and do it well. I watched them in college and on numerous occasions they took over games for their teams and won them. That is why they were drafted...right?
I will also state that a reasonable number of Celtics point guards I watched play from Cousy to today were not "long" in any way shape or form.
If the opponent attacks the "small point guard" things can be done.... as there are plenty of smaller PG's out there and still more with shiny sparkly championship rings on their fingers.
