Kravstov has a very funky release. I actually think there is a video floating around of Valiquette talking about why goalies have such a hard time reading it. He can put pregnant pauses into his shots that makes goalies second guess his placement.
Five hole shots are usually snap-shots with hands out in front of the body to catch goalies off guard, but Vitaly brings it back like a traditional wrist shot which signals “upstairs”, before following through with the actual release by his wrists at the end of the shooting motion. He either puts it five-hole(if it’s available) or low blocker.
Ultimately, I think Kravstov will not be able to lean on it as much as he did in the KHL, but at the end of his NHL career, Loffen will be able to make a 3:30 second tribute to him shooting five-hole, set to a Metallica song off of Re-Load or something.
