No you're right about this. PGs are underappreciated in Buzzerbeater. There are good PGs who average close to or over 10 APG but they are rare. Part of the reason is that people don't train passing all that much. There are a lot of guard skills to train and OD, JS and JR are preferred by most - so you'll find a lot of combo guards playing the point in this game. Otherwise if you create a Rondo like PG who is a great passer but can't shoot you'll find that he still takes a lot of shots and ends up with a shooting % of around 30-35. The game engine doesn't reward such PGs so as things stand you're better off not creating a PG with the type of skillset you described.
