Nation's Tallest QB in High School?

If he stays with football & had to change positions,like become a receiver,he'd be a big target not seen since Harold Carmichael & Morris Stroud. If he stays at QB,even if his arm isn't that strong,who is tall enough to knock down any of his passes?
 
Dan McGuire was 6'7" I think and he really didn't do much after his college career, often guys that are taller/bigger than the majority often don't pan out.
