Caufield is a better skater, quicker, better shot, then Locke. Locke was a heck of a play maker, he could dish the puck for sure but was just too slow, poor skater.
Caufield has his issues for sure, I don't think he will ever be a guy you put on the PK or known for his D, but the kid can shoot with the best of them, and is such a smart player in the offensive zone. The way he gets open despite everyone knowing if the puck is on his stick they are in trouble. He doesn't often get hit hard as he does a good job of avoiding the big hits despite having a target on his back. That said he will need to work on getting quicker, stronger, just like Gallagher did when he turned pro.
