His arm is legit, I can't lie. He threw a ball at a Clemson that was an absolute dime. The ball is pretty coming out of his hand.
His size leaves a lot to be desired. The scouting agencies list him as 6'4 215. I think those are overestimated. I don't believe them one bit. He looks 6'2ish 190lbs seeing him play on TV. What gives him his hype and recognition is his last name.
Don't compare Ahmmon to him. Ahmmon was playing in the 8A division at Wellington. He played against good competition and did numbers. Arch is playing at a private school that doesn't even play a national schedule. They mostly play against other private schools. I think Quinn Ewers is a better prospect than Arch.
Playing against top competition is an important piece to the puzzle. Seeing how an athlete competes against other top competition will tell you a lot. Does he fold when the pressure is on, does he elevate the play of his teammates, does he know how to lead through adversity? All of these are critical questions that get answered playing against the best out there.
I'm not saying Arch will be a flop or bust, I just don't see why he's so hyped up outside of his last name.
