That's an excellent point about how rare it is to have elite 40 speed and elite 3 cone speed.Waddle for me. Kid is a very rare physical talent.
There is a reason Waddle gets compared to Hill. The lazy one is the height and 4.3 speed. But I'd you look at what the top scouts say about Waddle and breakdown more physical traits you see why Hill is the best comp.
First look at Hill and his physical trait. Everyone knows the 4.3 40 speed. But people leave out he also he has elite short area speed/quickness, 6.53 3 cone drill. It is very rare for a guy have 4.3 top end speed and run a sub 6.6 3 cone. Sucks we don't have Waddles numbers. But we know he is a 4.3 guy. And watch the film and the scouting reports. You always see/hear cat like quickness or amazing burst and change of direction. This is why Hill is the best comp. Not saying will be Hill but from a physical stand point Hill is the best comp. These traits allow Hill to play in the slot (short area quickness) or outside (elite deep speed) even though he is 5'8. Waddle also has played the slot and outside at Bama.
Fuller is a good WR but he is an outside speed WR (4.32 40). But doesn't have the size to be a jumbo slot (6' 185) or elite quickness (6.9 3 cone).
To me Waddle is just a bit of a physical freak top end speed with elite short area quickness. People here where always hoping for Grant to develop into a HR type but he is not a physical freak like Waddle. Grant had a 4.37 40 but a 7.03 3 cone. It is almost impossible to find a Hill type freak 4.3 40 with a sub 6.6 3 cone and I think Waddle is one if them.
