your not really arguing what im saying, your agreeing with it, just drawing different conclusions. i said those championship teams had 2/3 guys under 5/9, and you seem to agree by listing 2/3 guys. but even they are not 5'6 or 5'7. 5'9 is not that big of a deal for a 16 year old ,but 5'6, i dont see many 5'6 or 5'7 guys that end up being the lead players on championship teams that were drafted in the top 40 of the draft. hayes is great, but he was 5'9 in his draft year out of honeybaked, diaco is a great player, but he was drafted in the 6th, not the 1st.
we seemingly are talking about 2 different things. im not saying small guys are bad, im saying that you need to target them in the right spot, hayes and diaco are great examples of guys taken after the top 80 who became great players. thats where you target those players, finding guys that play with skill and are over 6ft is so hard that you need to put a premium on them right away, because you wont find them later on. you will find the smaller guys later on, there are tons of guys taken in the mid to late round that are successful under 5'8, not so much forwards over 6ft after the 6th. teams like hamilton where great with those guys as secondary players riding the other players with some size that where taken higher. smart and effective drafting by hamilton.
you also need to be aware of team dynamic, team play, defensive positioning and such with your coaches when drafting, you may think that a 5'7 d is outstanding, but if your team structure relies on d with long reaches and taking away time and space with active sticks and gaps, the 5'7 d doesnt fit the team make up.
