Everything I have heard indicates that Utopo is extremely fast. He was always getting into the backfeild based on his quickness and was named DLman of the year in SoCal based on this charachteristic. The knock is he is a bit undersized: too light for a NT; too short for a DE. I personally think he is going to be one of those kids where size does not matter in the end- he will be a good DE.
Also, Nix might be bettern than Cody, who knows, but I don't like the comparison. Cody, like the Fridge before him, was one of those extremely, extremely rare birds who can still dunk at 400 lbs. He had to fight his way down to 350. Nix is a natural 300 lbs (which is still huge), but he is nowhere close to 350 lbs. IMO, this makes them totally differnt. Nix is a prototypical NT while Cody was an absolutely enormous freak of nature. Its like the difference between a fast 6'3" WR and fast 6'7" WR, or a true 4.4 forty and a true 4.2 forty. Hardly anyone could catch Golden, but he was still no Rocket (though he had better hands!).
