Yes, if Lonzo Ball was there at #3 I'd trade #5 and #10 to get him without hesitation.
You said about Ball: " He's got funky shot, the inability to turn the corner or penetrate consistently, struggles to guard quick PGs and hasn't shown that he can be nearly as effective in the half court and running the pick and roll.....Now you say you'd trade #5 and #10 for him?!?
What am I missing?!?
If you would be willing to make this deal (two Top 10 picks in loaded draft, potentially Fox and Collins) then you are projecting Ball as All-Star to justify your valuation. But you also just said you don't know if he will a star or solid pro? Your logic is all over the place, i.e. illogical. You either need to go all-in on Ball and project him as transcendent talent or reconsider how many assets you would hypothetically give up for him.
Among the reasons I am down on Ball since I first started to scout him (before he got schooled in tourney) is because he is lanky player. He has a higher center of gravity. His lateral mobility is compromised. Now he does use quick choppy steps but smaller guards are going to blow by unless his defensive anticipation is consistently extraordinary.
He has some separation ability with juke moves but he has a high dribble and junk to his game. I saw a player vs Kentucky who was SCARED to expose his dribble to Fox or else get picked. Ball gives up his dribble too soon instead of maintaining dribble under pressure and deep penetration into lane. Then if you watch his highlight clips you will see that a lot of plays are under little to NO ball pressure. This is because of quality of opponent AND the attention his teammates demanded.
Where does this leave us? Talented passer. Good court vision. Ricky Rubio-esque with more range on his shot. But with that corkscrew jumper are you going to trust that shot? I don't trust it. Now maybe I am wrong. But I don't think so. All you can do when drafting is bet probabilities. It is probable Ball maxes out as Rubio with a better shot and poorer defender, a 8/10/5 with average efficiency. That's near bust relative to being picked Top 5 and certainly not someone you'd relinquish 5th and 10th pick. I will bet my reputation Fox will be the better pro next year and rest of their careers.
If you can get Fox at #5 vs Ball at #3 plus #10, then you are effectively trading for the lesser player AND giving away the 10th pick for free! Sorry that does not jive.
